"Bigfoot" was an afterthought when he stepped into the cage with Overeem in February. At least, he was in Overeem's mind -- which led the Dutch heavyweight to mess around with his hands down until Silva decided to make him pay in the third round. Silva should not be dismissed by anyone. His unique combination of size, power, skill and athleticism is potent. Up next: UFC heavyweight champion Cain Velasquez, a rematch of a May 2012 contest in which Silva was overwhelmed in less than four minutes. The winner reigns as UFC and linear heavyweight champ.
