Mir benefitted from a stand up from hits to the back of the head. He was about to be pounded into oblivion.
Carwin is a stud, and I believe has the tools to beat Lesnar. JDS, Cain and Carwin along with the Frate trane gives Zuffa three good heavyweights. Brock was rocked by Randy and Mir on his feet, if he is to win, he needs to put Carwin on his back.
