51. Tiger Woods ($45.5 million)

Athlete

The 14-time major winner turned 40 in December 2015 and is feeling his mortality on the golf course, playing only 18 events since the start 2014 and making just six cuts. Woods built a fortune on endorsements with the likes of AT&T, Buick, Nike and Gatorade. All of those companies have left him, but Nike remains--and pays him more than $20 million a year. Other current partners include Hero MotoCorp, Kowa, Rolex and Upper Deck.
