Because we're talking about the UFC and not some bush league. Besides Sonnen lost to Filho and then cried about how he did'nt give up after he squealed to the submission. Even Dana White said it was the correct decision because Sonnen was so blatantly full of it.
Sonnen is one of the least accomplished if not the least accomplished fighters at LHW, hardly elite. He's above average at wrestling but still only has an average record at MW on his resume, this alone speaks volumes about what his skill level really is.
average resume at MW?? in 4 and a half years the only losses the guy has is to the two best fighters in the world in 2 different divisions and 1 of those guys he was 2 min away from beating. At MW he has some of the most dominating wrestling based wins in MMA history and this was when those guys had tons of momentum. One of the few guys to go UP in weight and not down in weight for competition and he just beat Shogun more impressively then any of his previous opponents have and Shogun has been facing some really tough competition and putting up competitive fights.
But he is just middle of the road same as all the guys he is beating left and right.
Okay Boom..... Okay.......
