Bummer, but not shocking...
I'm interested in Overeem, Rogers, and Werdum...and Barnett in Japan (I'm sure). I'm pissed that we don't get to see Fedor expose Lesnar, but the guys he'll be fighting are in the same group with most of the other guys the UFC has to offer (right now at least). The UFC has some nice up and coming fighters, but it's not like the stash of guys are much better than what SF can throw at him.
Lesnar - would love to see it due to the hype factor, but there is still a lot we don't know about Lesnar
Couture - give me a break...not at this point in his career
Mir - severely over-rated after beating a depleted Nog...Lesnar proved that
Carwin - love Carwin, but he's got some big holes in his game (Gonzaga almost exposed them). He could matchup well with Lesnar though based on having similar strengths and weaknesses.
Cain - great chin and wrestling, but not much else at this point. Kongo torched him standing.
Gonzaga - no heart
Dos Santos - we'll see
Nog - already beat him, no interest
CC - already beat him, no interest (Dos Santos is going to end this UFC run I'm afraid)
