Junior Dos Santos Vs Shane Carwin winner?

Carwin has been some doing some intense cardio work after he gassed out in the 2nd round in his loss to Brock Lesnar. I think you are going to see a more fit Carwin in the fight tomorrow with the same intensity and knockout power that he possessed before. I see this fight ending in the first or second round with Carwin's hand raised in victory. Most likely by a knockout. I don't see a submission by "either" fighter in this brawl...and it "will" be a brawl. As far as a Carwin vs Cain Velasquez fight, that's a tough call. I wouldn't know how to predict that one until I see Carwin's performance against Dos Santos tomorrow night.
