Well, I've already seen Brock beat to a bloody pulp... twice. Same with Bisping but only once. I guess a Nick Diaz tops my list now.
I'm always down to see Bisping get knocked out. Loved it when Hendo put him to sleep and when Wanderlei dropped him late in that fight. Even laughed when Kang dropped him. I expect Vitor to put Bisping out as well, that should be sweet.
But I'm a Nick Diaz fan. Even though I completely understand why people hate the guy.
Clay Guida hands down.
