I WANT Carwin to win but I think Mir has this one, he's put on so much weight since his last fight, he's massive and apparently everyone thinks that's all Brock has on Mir, is weight. We will see, I sort of want Mir to win so that we can see a complete trilogy between Lesnar and Mir.
As for predictions:
GSP vs. Hardy - GSP (unanimous decision)
Mir vs. Carwin - Mir second round via submission.
Alves vs. Fitch - Alves (2nd round TKO)
Diaz vs. Markham - Diaz (2nd round TKO - remember Hardy vs Markham? that was brutal, lol..)
Those are the only fights I remember off the top of my head.
