In honor of the Super Bowl, I am posting Sports Illustrated's Fortunate 50 top-earning American athletes (earnings include salary, winnings, bonuses, and endorsements). However, only one of the players in today's game made the list, Tom Brady of the New England Patriots, Rank: 47.
I found a nice table of this data on SportsColumn.com. Salaries are based on current or most recently completed seasons (exception: 2007 for NFL). For winnings-based sports (auto racing, golf, tennis), 2006 calendar year amounts used.
