 Herschel Walker has already had many diverse chapters in a fascinating sports life. He was one of the greatest college football players of all time while at the University of Georgia, an NFL star, an Olympic bobsledder, and most recently, he's dabbled as a mixed martial artist.

But at 48 years old, Walker is still looking to athletically challenge himself, and his latest thought is a doozy: he's considering an NFL comeback.
