Chris Weidman has been doubted his entire career. No one expected 'The All-American' to dethrone MMA legend Anderson Silva in 2013, but he did.
Weidman's second-round knockout of Silva was deemed a fluke, so the Serra-Longo product accepted an immediate rematch and finished 'The Spider' again in the same round -- this time with a checked kick that left Silva agonizing in pain with a broken leg.
Weidman went on to defend the middleweight title another two times before his thirteen-fight win streak was ended by former Strikeforce champ Luke Rockhold.
