Man, I keep going back in forth on this. My mind keeps telling me to pick Carwin. 12-0 all ending in the first round. Crazy power, really good submissions too. 7 ko's 5 submissions. Brock hasn't fought a guy as big as Carwin. But something tells me that Brock will win. I'm thinking Brock will hit Carwin with a devestating shot, ,putting Carwin on his back. Brock pounces on him, fight gets called. Brock wins TKO. So I'm gonna hesitantly pick Brock Lesnar. Who ya got?
