you can't take too much away from either fighter, yet it's blatantly obvious that both need serious work before being championship caliber contenders.
I think cain has a good chin since he was able to get a takedown mere seconds after being rocked twice, however he needs some serious standing defense before facing tougher competition, he needs more power on the ground, and submission skills, for the amount of time he had dominant position on the ground, and the fact that he was uncapable of finishing the fight is a slight detractor.
It also says that kongo is tough as nails, but seriously got exposed on the ground. imagine a competitors interpretation of that fight.
I'd like to see carwin vs. cain.
