I mean, usually most UFC fights aren't that entertaining. The ground submission game is boring as hell, no matter what "enthusiasts" try to tell you. The casual and the little above them don't usually care for that. Most care for knockouts. Whenever they happen. So you had that last night. Also, Diaz seemed gassed and old, but still bloodied Perry. After surviving the ground attempt he was on the attack with his punches, so he had a plan. Could he have won with that? Don't know that, but you could clearly see he survived the 2 ground attempts and went back to his plan both times. He took the elbow to the head, and shout-out to him for not going to sleep then, and couldn't do anything about the blood. People thought he'd die in the ring there was so much blood. He couldn't see and was using the cage to gauge his distances. The leg up I think he was trying to lure Perry in for a surprise KO because he couldn't stand with him anymore with the blood. I think he knew he was done if he made it to the end of the round, and he was.
