I've watched this fight three times now, and it's obvious that Sakara blatantly laid down. I think he may have done it do avoid getting knocked out, because he took a nice uppercut earlier that seemed to hurt him a bit. But ****, he paid for it.
McFedries didn't seem overly cocky to me, just happy as hell that he won, and he seems like he's ready to throw with anyone in the UFC. Looking forward to seeing more of him.
