#13 Arizona State Sun Devils





HEAD COACH: Todd Graham, 28-12 (3 years) | OFF. COORDINATOR: Mike Norvell | DEF. COORDINATOR: Todd Graham, Keith Patterson

Arizona State has won 20 games over the last two seasons and has finished as a top 25 team in back-to-back years under coach Todd Graham. And even with a few losses on both sides of the ball, the Sun Devils should be in contention for the Pac-12 South title once again in 2015. Quarterback Mike Bercovici should have a breakout year in his first as the starter, while the defense will be an aggressive group with seven returning starters.

Previewing Arizona State’s Offense for 2015 

Usually, when a team replaces a three-year starter at quarterback, there’s going to be a drop-off. But that’s not the case at ASU. In three relief starts last year, Mike Bercovici proved he could be an elite quarterback; he has a strong arm and shows great leadership. He’s not as mobile as predecessor Taylor Kelly, so the Sun Devils will tweak their offense to suit his skills.

ASU will lean more on its running game, and it has the horses to do so, with three backs — Demario Richard, two-way player Kalen Ballage and speedster Gump Hayes — capable of doing damage. Going to the ground first also makes sense, because the two big question marks on offense most affect the passing game. ASU has to replace both of its starting tackles, and the wide receiver position has been decimated with Jaelen Strong going to the NFL and Cameron Smith sidelined the entire season after knee surgery. D.J. Foster, now a full-time slot receiver after splitting time between tailback/receiver the last three seasons, will be Bercovici’s No. 1 target. The Sun Devils picked up a late addition in the spring in UCLA transfer Devin Lucien, which gives Bercovici another proven target.

ASU lost a couple of key players in defensive lineman Marcus Hardison and safety Damarious Randall, but coach Todd Graham has recruited so well that replacements should be able to step right in.

The strength of the defense is the back seven. ASU can rotate five linebackers without much drop-off. Keep an eye on sophomores Christian Sam and DJ Calhoun; they were pressing for starting positions in spring ball and have the sideline-to-sideline quickness Graham loves at the position.

ASU returns three starters in the secondary, and James Johnson will help negate the loss of Randall.

If there’s a concern, it’s the lack of a true pass rusher up front. Four-star junior college recruit Davon Durant was plugged in to be the Devil-backer — primarily a pass-rusher in ASU’s scheme — but he was suspended indefinitely following an arrest on allegations of domestic abuse.

Graham won’t back off despite the lack of an elite pass-rushing threat. Instead, he’ll dial up a variety of blitzes to try to keep quarterbacks guessing. It’s a dangerous gambit — Oregon State had three touchdowns of at least 35 yards in its 35–27 victory over the Devils last year — but Graham will remain aggressive. It’s who he is and how he coaches.

The kicking game will be solid with punter Matt Haack and placekicker Zane Gonzalez, but the mission for new special teams coordinator Shawn Slocum is to improve the return game, which has been a disaster for ASU. The answer might be Hayes, who terrorized the defense in practices leading up to last year’s Sun Bowl. Hayes has the speed and natural running instincts to be a threat every time he touches the ball.

Final Analysis

In three seasons Graham has turned an underachieving program into one that regularly cranks out 10-win seasons. This year should be no different. ASU returns 12 starters, and that number doesn’t include Bercovici. There are some worries — most notably at wide receiver and offensive tackle — but the Sun Devils have the talent and the coaching to contend for the Pac-12 title.

The schedule is daunting, particularly early in the season. ASU opens against Texas A&M in Houston, and three of its first four conference games are USC, at UCLA and at Utah. But if the Sun Devils can somehow come out of that stretch with just one conference loss, they will be in great shape to win the Pac-12 South. Three of their final five games are at home, and the only road contests are against California and Washington State.

#12 Notre Dame Fighting Irish



Independents PREDICTION


HEAD COACH: Brian Kelly, 45-20 (5 years) | OFF. COORDINATOR: Mike Sanford | DEF. COORDINATOR: Brian VanGorder

Notre Dame has won at least eight games in each of Brian Kelly’s five seasons, but the Fighting Irish are looking to rebound after an 8-5 campaign in 2014. After a 7-1 start, Notre Dame lost four out of its last five games. Injuries and youth hindered the Fighting Irish last season, but the experience and additional depth should pay dividends for Kelly’s team in 2015.

Follow Athlon Sports on Twitter: @AthlonSports

Previewing Notre Dame’s Offense for 2015 

Notre Dame showed marked improvement in scoring (from 27.2 ppg in 2013 to 32.8 in 2014) and total offense (405.8 ypg to 444.9), and all but four starters return in ’15. The challenge is maximizing the assets. And there’s clarity at the quarterback after uncertainty surrounded this position at the end of spring ball. Everett Golson transferred in early May, which leaves the starting job to promising sophomore Malik Zaire.

The offensive line, led by veterans Ronnie Stanley (left tackle), Nick Martin (center) and Steve Elmer (right guard), is the foundation upon which the Irish attack is built.

There appear to be plenty of skill-position buttons to push, starting with wideout Will Fuller, who exploded as a sophomore with 76 receptions for 1,094 yards and a school-record-tying 15 touchdowns. Running back Tarean Folston also had a quality sophomore season (889 yards rushing). Now the challenge is to get former five-star recruit Greg Bryant in the mix with Folston.

Weapons abound in the receiving corps, but reliability is the challenge. Corey Robinson, Chris Brown and Amir Carlisle have yet to put together consistent seasons. C.J. Prosise offers versatility in the backfield and receiving prowess from the slot. Durham Smythe is the heir apparent to a dynamic tight end tradition.

Previewing Notre Dame’s Defense for 2015

It was a tale of two defenses in 2014, but most of the unit is back. The hope is the group that held its first five opponents to 60 points (12.0 ppg) will show itself more than the defense that surrendered 319 points (39.8 ppg) against the last eight opponents.

Ringleaders include two-time captain/defensive tackle Sheldon Day (7.5 tackles for a loss, nine QB hurries), linebacker Jaylon Smith (team-leading 112 tackles, 9.0 tackles for a loss) and linebacker Joe Schmidt, who garnered defensive MVP honors despite missing the last five games with a broken ankle.

To get to the next level, the Irish will need a more stout performance up front than the 26 sacks of 2014. Defensive end Isaac Rochell (7.5 tackles for a loss, 10 QB hurries) emerged as a building block as a sophomore. Nose tackle Jarron Jones, also coming off a significant foot injury, forms a dynamic one-two punch with Day up the middle. The pass rush should come from ends Romeo Okwara and Andrew Trumbetti, among several candidates. Look for freshman nose tackle Jerry Tillery to make an impact.

The return of cornerback KeiVarae Russell after his academic suspension is huge. He’ll pair with Cole Luke, who tied for the team lead with four interceptions to go with 15 passes defensed and 11 broken up. Safeties Elijah Shumate and Max Redfield struggled a good portion of the time in 2014, but they’re back and their troubles were not for a lack of talent.

Previewing Notre Dame’s Specialists for 2015

Do-everything Kyle Brindza is gone after a quality but often-erratic career with the Irish. There could be a drop-off punting with Tyler Newsome moving into the lineup, but highly touted true freshman kicker Justin Yoon has the skills to hit the ground running. Fuller, Carlisle and Bryant are the likely return men.

Final Analysis 

It’s the sixth year of the Brian Kelly regime, and in only one of the previous five — 2012 when the Irish played for the national title vs. Alabama — has Notre Dame finished with fewer than four losses.

This is the deepest, most well-equipped team Kelly has fielded. If the Irish can maximize Zaire’s talents at quarterback, establish a consistent ground game and play more stout up front defensively, this season should resemble 2012 more than any of the others under Kelly. That would mean playing in a New Year’s Day bowl if not contending for a playoff spot.


#14 Clemson Tigers





HEAD COACH: Dabo Swinney, 61-26 (6+ years) | OFF. COORDINATOR: Jeff Scott, Tony Elliott | DEF. COORDINATOR: Marion Hobby, Brent Venables

Clemson has won at least 10 games in four consecutive seasons, and even with personnel losses on both sides of the ball, the Tigers should be in contention for the ACC title in 2015. Quarterback Deshaun Watson should be at full strength from a torn ACL by the fall, and the rising star will be surrounded by a deep group of skill players. Only two starters return on one of the nation’s top defenses. However, Clemson has recruited well, and there’s still talent on the roster to replace some of last year’s stars.

Previewing Clemson’s Offense for 2015

The moment Clemson fans had dreaded for the better part of four years finally arrived in December when offensive coordinator Chad Morris became SMU’s new head coach. But the Tigers’ offense shouldn’t look that different as long as star sophomore quarterback Deshaun Watson stays healthy. Coach Dabo Swinney opted for continuity, elevating running backs coach Tony Elliott and wide receivers coach Jeff Scott to co-offensive coordinators.

Watson is the key. In eight games (five starts), he threw for 1,466 yards with 14 touchdowns against two interceptions, but he missed nearly five full games with a broken finger and later a torn ACL. He had surgery in December and will be healthy for the season opener. With Cole Stoudt at the helm, the offense largely struggled. Clemson averaged 30.8 points per game, No. 51 nationally, and ranked 110th in red zone offense.

Watson is a dynamic dual threat with excellent targets in Mike Williams and Artavis Scott, who combined for 1,995 yards with 14 touchdowns on 133 receptions a year ago. Wayne Gallman leads an improving backfield as a powerful speed back. There are questions about a line that must replace both starting guards, and true freshman Mitch Hyatt is expected to start at left tackle after Isaiah Battle declared for the NFL supplemental draft. But if Watson is healthy, the Tigers’ offense should be scary good.

Brent Venables raised some eyebrows when he left Oklahoma to take over Clemson’s struggling defense in January 2012; but three years later, it looks like a brilliant move. Last fall, the Tigers had the nation’s top overall defense, allowing 260.8 yards per game, and the No. 3 scoring defense, yielding 16.7 points per game. The challenge? Repeating the feat after losing nearly the entire defensive line two-deep (including Clemson’s career sack leader Vic Beasley) as well as middle linebacker Stephone Anthony, the team’s leading tackler.

Junior defensive end Shaq Lawson will be expected to take his game to the next level: He was a freshman All-American two years ago and had 3.5 sacks as a reserve last fall.

Junior Ben Boulware, one of the defense’s most intense players, will step into a lead role at weak-side linebacker. He and senior B.J. Goodson will have to carry bigger loads while a pair of hard-hitting redshirt freshmen — Kendall Joseph and Korie Rogers — provide depth.

The secondary will be a major strength. Sophomore cornerback Mackensie Alexander established himself as one of the ACC’s top cornerbacks with excellent shutdown ability.  Safety Jayron Kearse is an athletic specimen who is expected to take the next step this fall. Clemson was No. 2 nationally in pass defense a year ago, allowing 157.4 passing yards per game, and the defense will lean on the secondary again while the new defensive line gets acclimated.

Previewing Clemson’s Specialists for 2015

Clemson’s only early draft departure was junior punter Bradley Pinion, who averaged 42.6 yards per boot. His replacement, junior Andy Teasdall, had two punts for 87 yards last fall. Kicker Ammon Lakip struggled initially while replacing Chandler Catanzaro, but he recovered to make 21-of-28 field goals and finish as a Lou Groza Award semifinalist.

Final Analysis 

Under Dabo Swinney, Clemson has developed into one of the nation’s steadiest programs, winning 42 games over the last four seasons with an ACC title and bowl wins over LSU, Ohio State and Oklahoma. Now is the time for the Tigers to take the next step and make a run at the College Football Playoff. This group has the talent and the schedule to win the ACC. From there, the sky is the limit.

#15 LSU Tigers





HEAD COACH: Les Miles, 103-29 (10 years) | OFF. COORDINATOR: Cam Cameron | DEF. COORDINATOR: Kevin Steele

LSU owns one of the nation’s most talented rosters, but key question marks remain for Les Miles’ team in 2015. Will the offense take a step forward after ranking 13th in the SEC in scoring last season? Getting better play from its quarterbacks would help, but the Tigers finished spring with uncertainty under center. On defense, LSU has a new coordinator in Kevin Steele and needs to revive a pass rush that registered only 19 sacks in 2014.

Previewing LSU’s Offense for 2015

Another spring in Baton Rouge and another quarterback controversy after 2014 provided little to no clarity in the race between Anthony Jennings and Brandon Harris. Coach Les Miles said the two quarterbacks split the snaps in the spring but indicated that Jennings — who completed only 49 percent of his passes last season — had the upper hand in closed scrimmages. Maturity issues and a failure to learn the playbook plagued Harris last season, and he’s admitted as much. Jennings heads into the fall as the frontrunner, but the position is far from settled.

Miles claims that tailback Leonard Fournette is bigger and stronger after almost a full year in the Tigers’ strength and conditioning program, so expect the Tigers to abandon the committee approach and allow the former five-star recruit to handle the majority of the work. He is poised for a huge season.

Poor quarterback play limited the production of a young but talented group of wide receivers. Travin Dural, who led the team with 37 receptions for 758 yards, was the only Tiger to catch more than 17 passes in 2014. Malachi Dupre, a top recruit in 2014, is poised for a breakout season if he can stay healthy.

The Tigers lose two valuable members of their offensive line but are well-equipped to move forward without taking a step back. Jerald Hawkins has the unenviable task of replacing three-year starter La’el Collins at left tackle. Hawkins has started every game he’s played at LSU but now must shift from right to left tackle.

The moniker “DB U.” is tossed around Baton Rouge as each new crop of defensive backs expects to be as good as their past teammates now in the NFL. Cornerback Tre’Davious White, the leader of not only the secondary but also the entire defense, is bringing along Ed Paris and early enrollee Kevin Toliver II to carry on the tradition. “We’re still DB U. It’s just different cats,” Paris said during the spring. Jalen Mills, a former Freshman All-American as a cornerback, and Jamal Adams will form a dynamic safety duo in what figures to be one of the most talented secondaries in the SEC.

Issues surrounded the inexperienced LSU defensive line from the start in 2014 as an endless rotation of players made it difficult for the unit to have any continuity. Christian LaCouture and Davon Godchaux have settled in nicely at defensive tackle, but there is concern at defensive end. With new coordinator Kevin Steele’s experience in a 3-4 base defense, the Tigers may play more three-man fronts as they continue to search for playmaking ends.

The insertion of true freshman Kendell Beckwith into the lineup at Florida ignited the LSU linebacker corps, a unit maligned during much of 2014 for its inability to play sideline to sideline. Beckwith, the team’s second-leading tackler in 2014, brings a youthful energy and a ton of athleticism to the middle linebacker spot.

The once-automatic Colby Delahoussaye struggled late in his sophomore season, missing three of his final four attempts. He will battle classmate Trent Domingue for the placekicking duties in preseason camp. Jamie Keehn returns as the Tigers’ punter.

Final Analysis 

It’s pretty simple: LSU needs much better play from the quarterback position in 2015. Whoever gets the starting nod must improve on an anemic passing attack that failed to throw for more than 150 yards in seven of eight SEC games. Fournette is a star, but he can’t carry an entire offense on those broad shoulders. The defense, led by a top-flight secondary, will be strong — if not elite like LSU defenses of the recent past. The Tigers are talented enough to be a factor in the rugged SEC West — only if the passing offense improves.

#16 Arkansas Razorbacks





HEAD COACH: Bret Bielema, 10-15 (2 years) | OFF. COORDINATOR: Dan Enos | DEF. COORDINATOR: Robb Smith

Arkansas showed significant improvement in Bret Bielema’s second year and finished the 2014 season by winning four out of its last six games. The Razorbacks should be even better in 2015 with the return of quarterback Brandon Allen, one of the nation’s top backfields and offensive lines. The front seven on defense must be retooled, but there’s enough talent to keep this unit near the top of the SEC.

Follow Athlon Sports on Twitter: @AthlonSports

Previewing Arkansas’ Offense for 2015

Brandon Allen is in line to become Arkansas’ first three-year starting quarterback since Matt Jones (2002-04), but he’s working on his fourth offensive coordinator in five years with the arrival of Dan Enos. If Allen marginally improves on his 2014 passing numbers — 2,285 yards, 20 touchdowns, five interceptions — the Razorbacks could make a huge leap.

Arkansas sports the FBS’ only tandem 1,000-yard rushers from last season in Jonathan Williams (1,190 yards) and Alex Collins (1,100), who each rushed for 12 touchdowns. The duo should be just as dynamic this fall running behind a line that returns four starters. The front wall has undergone a shake-up, with former guard Denver Kirkland now at left tackle and Dan Skipper swapping sides to right tackle. Left guard Sebastian Tretola, who gained national publicity for his touchdown pass on a fake field goal last year, returns in better physical condition next to center Mitch Smothers. Frank Ragnow is the top candidate to take over at right guard, and the Razorbacks should have quality depth.

Keon Hatcher returned to lead the receiving corps, which is in need of game-breaking talent. Signee Dominique Reed and redshirt freshman Jojo Robinson should provide a spark to a unit that also brings back Jared Cornelius, Cody Hollister, Drew Morgan and converted quarterback Damon Mitchell.

Hunter Henry again leads the tight end corps, which also features Jeremy Sprinkle and signee Will Gragg, the brother of ex-Hog Chris Gragg of the Buffalo Bills.

Arkansas shook off about a decade of sluggish play from its defense to rank 10th nationally in yards allowed per game, an improvement of 66 spots. Second-year coordinator Robb Smith re-upped with a handsome raise and is confident the Razorbacks can plug rising stars into the system and remain productive despite the loss of key players such as Trey Flowers, Darius Philon, Martrell Spaight and Alan Turner.

Up front, breakout star Taiwan Johnson has moved from nose guard to defensive tackle to create room for Bijhon Jackson and DeMarcus Hodge. Ends Deatrich Wise Jr. and JaMichael Winston are prepared for larger roles and the leadership mantle. Junior college transfer Jeremiah Ledbetter should have an impact.

Brooks Ellis slides from middle linebacker to the weak-side spot from which Spaight racked up an SEC-best 128 tackles. Junior Josh Williams and sophomores Khalia Hackett and Randy Ramsey (if he returns from suspension) should have increased playing time at linebacker.

Corners Jared Collins, D.J. Dean and Henre’ Toliver have proven to be solid SEC cover men. Rohan Gaines brings veteran experience at strong safety, and sophomore Josh Liddell could be the kind of heavy-hitting free safety the Razorbacks have lacked for years.

Toby Baker and signee Blake Johnson are vying to replace punter Sam Irwin-Hill. Adam McFain has the experience edge over Lane Saling and Cole Hedlund for placekicking duties. Cornelius is the punt returner after showing promise as a freshman, and Hatcher has experience on kickoff returns.

Final Analysis

Arkansas should be more dynamic and more efficient with Allen back for his third season as the starter operating in front of a top-flight offensive line. The defense, despite some key losses in the front seven, should once again be strong. To emerge as a legitimate contender in the rough-and-tumble SEC West, the Hogs must find a way to win on the road in league play (something they haven’t done since October 2012) and learn how to win close games (they haven’t won an SEC game decided by a touchdown or less since October 2011).

#17 Oklahoma Sooners





HEAD COACH: Bob Stoops, 168-44 (16 years) | OFF. COORDINATOR: Lincoln Riley | DEF. COORDINATOR: Mike Stoops

Oklahoma entered 2014 with high expectations and hopes of winning the Big 12 title. But the Sooners finished 8-5 and a 5-4 mark in conference play, forcing coach Bob Stoops to make a few changes to his staff. Lincoln Riley is now the play-caller on offense and plans on implementing a spread attack similar to what he coordinated at East Carolina. However, the offense will still feature running back Samaje Perine. Oklahoma isn’t short on talent, but Stoops and his staff have to replace four starters on the offensive line and improve a secondary that allowed 24 passing plays of 30 yards or more in 2014.

Follow Athlon Sports on Twitter: @AthlonSports

Previewing Oklahoma’s Offense for 2015

When Lincoln Riley arrived to overhaul Oklahoma’s offense as coordinator, the immediate question was obvious: Who fit as a triggerman for the spread attack he used to create misery against better competition at East Carolina? That’s still the question, although indicators point to Baker Mayfield, the former Texas Tech walk-on and transfer.

None of four quarterbacks — Mayfield, returning starter Trevor Knight or youngsters Cody Thomas and Justice Hansen — did enough to seize the job in the spring. Mayfield looks the part as a pocket passer who has already directed the spread at Tech. But he was prone to throwing interceptions at Tech and tossed two in the spring game. “When I was able to get the ball in our receivers’ hands, they made plays for me,” Mayfield says. “Now I just have to keep improving and finding ways to get them the ball.”

If the quarterback concerns extend into the season, the Sooners always have Plan B. Or is it Plan A? The Big 12’s best back as a freshman a year ago, Samaje Perine is a throwback, downhill runner who can dominate and dictate games. Oklahoma rode him hard last fall when the passing game stalled, resulting in solid success, as he ran for a league-leading 1,713 yards and 21 touchdowns. The running game also features the speedy Alex Ross, as well as Joe Mixon, a five-star recruit forced to spend a year away from the team after an ugly off-the-field incident last summer.

Sterling Shepard provides a game-breaker at receiver, but it’s critical that others emerge to fit the four-wide scheme.

The offensive line has something to prove, too, and is working to find replacements at both tackles. Returning starters Ty Darlington at center and Nila Kasitati at guard provide a veteran core.

Order a copy of Athlon's 2015 Big 12 College Football Preview, which includes an in-depth look at all 10 teams, features and predictions for the upcoming season.

The defense presents a mix of star power and major question marks. And the questions begin up front, where the decision by Jordan Phillips to leave early for the NFL leaves a gaping hole at tackle. Sophomore Charles Walker alleviated some concern inside with a strong spring. And the ends are solid with Charles Tapper, Matt Dimon and D.J. Ward providing a versatile rotation. But will it be a dynamic front?

At linebacker, Eric Striker sets the tone of the defense as an attacking ball hawk and game-plan wrecker. A first-team All-Big 12 selection, Striker led the Sooners with 17 tackles for a loss and nine sacks. And Dominique Alexander and Jordan Evans return as the team’s top two tacklers, making the middle a major strength.

The secondary must improve, even with first team all-conference corner Zack Sanchez back to rule his side of the field. Sanchez led the team with six interceptions and eight pass breakups. Sophomore Steven Parker is a rising star at safety or as the nickel, but the Sooners are searching for reliable playmakers at the other corner and safety spots.

Related: Athlon's 2015 College Football Rankings: No. 1 to 128

Previewing Oklahoma’s Specialists for 2015

Replacements at placekicker and punter are needed, and both jobs could fall to incoming freshman Austin Seibert, who was ranked No. 1 at each spot by one recruiting service or another. The return game could be explosive, with Ross proving himself dangerous on kickoffs, averaging 31.2 per runback a year ago. Dede Westbrook and Shepard, slotted to return punts, are also dynamic with the ball in their hands.

Final Analysis

Much uncertainty surrounds the Sooners entering 2015. Can Mayfield efficiently engineer the offense? And if not, who can? Can the defense fix a leaky secondary that allowed too many big passing plays? The schedule is rough, too, with road games at Tennessee, Kansas State, Baylor and Oklahoma State. A lot of questions. And it’s unclear whether the Sooners have all the answers.
