There's a lot at stake at UFC 121 this weekend. Which fighters will prevail?
Brock Lesnar is always the main draw when he fights, and for good reason -- the former wrestler and football player presents an almost-unsolvable problem to opponents. His ground game has gotten far better, as his win over Shane Carwin showed, and he still possesses a hellacious strike. Cain Velasquez will be in the unenviable position of attempting to derail Lesnar's rise to prominence in the world of mixed martial arts, but Velasquez is no scrub. He's undefeated in the octagon and is fresh off a big win over Antonio Rodrigo Nogueria in February.
