Athlon Sports is going division by division, asking and (trying to) answering the biggest question for every team in the league entering the 2015 season.
Chicago: Is Jay Cutler your starting quarterback?
There are a lot of unknowns about the Bears with John Fox now running things in the Windy City. But it's hard to address any of the other issues while ignoring the flashing neon sign under center. Chicago can't rid itself of Jay Cutler (not for lack of trying), and, despite his much-deserved criticisms, the veteran is still a better option than a dozen other NFL starters. Fox and offensive coordinator Adam Gase certainly won't be married to the incumbent so the leash will be short. How a run-first, disciplinarian head coach meshes with a lackadaisical and frustrating quarterback will be fascinating. If Cutler and Gase can get on the same page, the Bears have a lot of weaponry to utilize.
Detroit: Can the defensive line be rebuilt?
The Lions' offense underachieved last fall but is loaded for bear in 2015. It's the NFL's No. 2-ranked defense that has major holes to fill. Ndamukong Suh, Nick Fairley and C.J. Mosley are gone off the defensive line. Haloti Ngata fills one role immediately but is turning 31 and posted the second fewest tackles in his career last season. Ziggy Ansah is a special talent but is still very young while free agents and rookies will be asked to step in and fill other voids. The linebackers are among the NFL's best and the secondary is finally rounding into form. But to stay elite, the Lions' defensive line has to prove it can reload after some major departures.
Green Bay: Organize the new faces on defense?
The Packers are loaded and picked by many to win the division, but there are holes on the defense. Longtime veteran starters A.J. Hawk and Tramon Williams are gone along with role players Davon House and Jamari Lattimore. B.J. Raji returns but the Packers need strides from first-round picks Datone Jones, Nick Perry, Ha Ha Clinton-Dix and Damarious Randall. The Packers used their first two picks this year on corners and selected Jake Ryan in the fourth round. Clay Matthews has excelled inside and out but his supporting cast — which is loaded with early draft picks — needs to step into more prominent roles.
Minnesota: Can the young talent develop quickly?
There is a lot of young talent on this team. In fact, the Vikings have made eight first=round picks in the last four drafts and all eight have Pro Bowl potential. This group doesn't include rookie starting middle linebacker Eric Kendricks or other young starters like Everson Griffen, Kyle Rudolph or Antone Exum. This team is poised for big things in the near future, but the question is can the future be 2015? Despite the new contract, Adrian Peterson may not be long for the Twin Cities but he has an extremely experienced offensive line and fresh legs. If Teddy Bridgewater and the other young talent develops quickly, this is a sneaky good playoff team. If not, All-Day could be in Dallas this time next year.
