Lesnar vs Carwin - If lesnar could get back withing 4 months this should happen instead of Carwin\Mir. I think Carwin would lose to a lot of top heavy weights so why risk the chance of this fight NEVER happening. He's the only guy in the UFC who can remotely counter Lesnars strength.
Velasquez vs Junior Dos Santos They both have that killer instinct toughness to them. Both are guys I can't picture losing... JDS has some hands though I'd give the edge to Cain and his wrestling ability plus undefeated hype mystique.
Frank Mur vs Nog 2 - Don't want either fighting for the title, let the best old news fighter win to continue.
