Most professional athletes pour themselves into their craft. Most realize at a young age what they are destined to do. They hone their skills to an incomparable level and then push it a little further.
However, a select few show elite talent in more than one discipline—and when they do, it's electric.
Remember where you were when you heard about Bo Jackson? Remember your quizzical reaction to a man capable of dominating two major sports?
With only 20 spots on the list, let's set a few ground rules. First, the athlete has to be a superstar in at least one of his or her sports. You won't see the likes of Scott Burrell (the only man to be taken in the first round of two different sports). His professional career didn't pan out well enough to consider him a superstar, so he's out.
Second: no high school studs. I know Allen Iverson led his high school football team to a state title, but he didn't play past the prep level. If you didn't show your skills in college or beyond, you don't count.
Lastly: Olympic medalists do count. There's nothing more admirable than representing your country on the world stage.
All right, let's get into it. These are the Best Multi-Sport Athletes of All Time.
