Bonafides From 2002-2012: UFC Middleweight Champion, Former Cage Rage Middleweight Champion, 22-3-0 (15 KOs, 3 Submissions)
Even though Anderson Silva has caught a few Ls (three, to be exact) during the Complex Decade, he's rebounded from his losses and established himself as the best pound-for-pound mixed martial artist in the world. He's currently toting a 15-match winning streak and hasn't lost a bout since George W. Bush was in the White House. Some complain that Silva becomes too stagnant once he feels that he has the fight won, but never underestimate the man they call "The Spider" because he can strike at any moment.
