My own list:
1.Lesnar
2.Carwin
3.Cain
4.Mir
5.Dos Santos
Dos Santos still needs to prove his ground game / takedown defense. I could be persuaded to switch Carwin and Cain, but I think that while Carwin's wrestling may be weaker, it's "good enough" for almost all opponents, and he has more power in his hands. So far, I'm liking the odds for Carwin against Mir, but I'm concerned that "UberMir" may be different enough from his earlier self that prediction is tough. Any other opinions on that fight?
