Sports Illustrated has compiled a list of the 50 highest paid U.S. athletes by salary, winnings, endorsements and appearance fees. Mayweather is #3 on the list with $60,250,000 made in 2009. What's crazy is that of the $60m only 250K came from endorsements. I think the reason Floyd is reluctant to fight Pacquiao is that the earnings from his fights accounts for almost all of his income and a loss could damage his ability to earn at his current level. Also, it seems like his behavior outside of the ring has made companies not want him associated with their products.
