45-0 for Floyd Mayweather Jr.

It wasn't unanimous, a decision the champ called "a joke," but it was a win nonetheless for the still undefeated Floyd Mayweather Jr. He thoroughly outboxed Canelo Alvarez, landing 232 of 505 punches to Alvarez's 117 of 526, but he won by majority decision because one judge scored the fight 114-114, when the others scored it 117-111 and 116-112. And not only did Money May laugh at the decision, he laughed all the way to the bank. The $41.5 million was his biggest guaranteed payday to date, and that's before his portion of the $20 million live gate and $100 million in pay-per-view buys.

Rounding out the top three are a pair of NFL quarterbacks who are considered two of the best in the game today. Aaron Rodgers schooled the Redskins' defense with a franchise record-tying day, while Peyton Manning showed his younger brother a thing or two, and in the process became the third QB in league history to reach 60,000 career passing yards.
