Carwin would give Brock a lot of problems. He's strong and hits like a freight train. No way Brock can toss him around like he's done to the other guys he's fought.Honestly, I wonder if there is any HW currently in the UFC that can compete with Lesnar. He is such a dominant fighter simply because of his sheer size/strength and athletic ability. His wrestling skills really help as well because he can take down anybody and then once he gets on top it's ground-n-pound time! Fedor is really the only one I see being able to beat Lesnar and Lesnar is probably the only HW I can see worth putting in the ring with Fedor. That fight would be HUGE like Rocky IV when Rocky Balboa fought Ivan Drago!:biggrin:Seriously, I think Brock is the real life American version of Ivan Drago from the movie, steroids and all!
Fedor would be like Rocky because he is so much smaller than Brock (by about 80lbs) and yet Fedor has the experience on his side as he has fought and beat some of the best in MMA.
Josh Barnett and Fedor would both destroy Brock. Josh because of size, strength, wrestling pedigree and overall experience. Fedor because he's so super skilled.
