When Anderson Silva fights Chris Weidman at UFC 162 next weekend, he will be putting his 17-fight win streak, consecutive wins record, and consecutive title defenses record on the line. Silva's last five fights have ended in a stoppage. He is the closest thing the UFC has to unbeatable.
But more and more MMA folks say Weidman is the guy who can take him out. He is undefeated, and has six wins by a stoppage. UFC welterweight champion Georges St-Pierre has trained with Weidman and said he will beat Silva. UFC commentator Joe Rogan said Weidman has the game to take out Silva. Frankie Edgar said he thinks Weidman will win, and noted BJJ expert Roger Gracie said Weidman can submit anyone, even Gracie.
