Some of the world's greatest athletes weren't just one-sport players; instead, they excelled in two (and sometimes in several). Of course, some athletes probably should have stuck with their main sport. Here's a look at the top 30 two-sport athletes of all time, ranked in order of their second best sport.
1. Jim Thorpe, track (Best sport: football)
One the all-time great athletes, Thorpe is a member of both the College and Pro Football Halls of Fame, and has been immortalized via the Jim Thorpe Award — given annually to the top defensive back in college football. But Thorpe was also a gold medalist in both the pentathlon and decathlon at the 1912 Stockholm Olympics.
2. Jim Brown, lacrosse (Best sport: football)
Arguably the greatest running back in history, Brown is a member of both the College and Pro Football Halls of Fame. The 6’2”, 230-pounder is a member of the National Lacrosse Hall of Fame and is considered by many to be the best athlete to ever play the sport.
3. Bob Hayes, football (Best sport: track)
“Bullet Bob” Hayes won the fastest man in the world, winning gold medals in the 100 meters and 4x100 meters at the 1964 Tokyo Olympics. Hayes then strapped on a helmet for the Dallas Cowboys, winning Super Bowl VI and was inducted into the Pro Football Hall of Fame.
4. Bo Jackson, baseball (Best sport: football)
Only Bo knows what might have been. The 1985 Heisman Trophy winner was a Pro Bowl running back for the L.A. Raiders and an All-Star outfielder for the Kansas City Royals — hitting 32 HRs and 105 RBIs in just 135 games in 1989 — before a hip injury derailed the out-of-this-world athlete.
5. Charlie Ward, football (Best sport: basketball)
Sure, Ward played 11 seasons in the NBA — starting at point guard for the New York Knicks’ Eastern Conference champs in 1999. But most know him as a Heisman Trophy winner and national champion quarterback at Florida State in 1993.
6. Babe Didrikson Zaharias, track (Best sport: golf)
A 10-time LPGA major champion and member of the World Golf Hall of Fame, Mildred Ella — better known as “Babe” — won gold medals in the 80-meter hurdles and javelin throw as well as a silver medal in the high jump at the 1932 Los Angeles Olympics.

The Big Kahuna won three Olympic medals in the 100-meter freestyle — taking gold at the 1912 Stockholm Olympics and 1920 Antwerp Olympics, and silver at the 1924 Paris Olympics — as well as a gold (1920) and silver (1912) in the 4x200-meter freestyle relay. But Mr. Hawaii was also the “Father of Surfing,” popularizing the longboard en route to becoming a member of the Surfing, Swimming and U.S. Olympic Halls of Fame.
8. Deion Sanders, baseball (Best sport: football)
A member of both the College and Pro Football Halls of Fame, Prime Time is considered the greatest cornerback in NFL history. A two-time Super Bowl champion, Sanders also played with the Atlanta Braves in the 1992 World Series and played parts of nine lightning-fast seasons in MLB.

A four-time MLB All-Star and 1957 World Series champion with the Milwaukee Braves, the 6’8”, 225-pound Conley also won three NBA championships with the Boston Celtics — becoming the only athlete in history to win world titles in two of the big four pro leagues.
10. Danny Ainge, baseball (Best sport: basketball)
The Wooden Award winner at BYU, Ainge won two NBA championships with the Celtics and was an All-Star in 1988. He also had a cup of coffee with the Toronto Blue Jays, playing three seasons from 1979-81.

20. Marion Jones, basketball (Best sport: track)
Once a golden girl, Jones’ reputation has since been tarnished by PED use and jail time.

22. Jimmy Graham, basketball (Best sport: football)
Played four years of basketball at the University of Miami but just one season of football at The U. No big deal, the 6’6”, 260-pound power forward has evolved into one of the NFL’s best tight ends, with 1,310 yards and 11 TDs for the New Orleans Saints in 2011.

28. Herschel Walker, mixed martial arts / bobsled (Best sport: football)
Known for always being in peak condition, Walker started his MMA career as a 48-year-old. The fifth-degree Taekwondo black belt is 2–0 with two TKOs on punches.

29. Scott Burrell, baseball (Best sport: basketball)
The only athlete selected in the first round of two of the big four sports’ drafts — Burrell went No. 20 overall to the Charlotte Hornets in the 1993 NBA Draft and No. 26 overall to the Seattle Mariners in the 1989 MLB Draft.
