For what it's worth: Dana came out and stated that Kimbo will fight in the UFC no matter what the outcome of TUF (seems strange that he would say this just before they broadcast the fight between Kimbo and Nelson). Nelson is probably the toughest draw and so early in the training that Kimbo's chance...
I have to go with Belfort for this one. Belfort has looked really great in his last three fights. He seems to have it together again. If the old Crocop from pride shows up, then I go with Crocop, although Dos Santos is a beast.
