Professional athletes walk away from money all of the time, but it's almost never to end up with less guaranteed money. It's considered a collosal fuckup whenever that happens (fumbling the bag).

Athlete's don't have nearly the same wiggle room for free thought. You go from guaranteed bag to guaranteed bag until you're too old to keep up.
