Did you guys watch the fight?? Sean lost to DDP, but beats up Khamzat...
I think the biggest difference was: Sean got up after each take down. He also managed his own takedowns in the process.
It's difficult for me to believe that Sean is so much stronger than DDP and that DDP's wrestling/Grappling, is so poor.
Very interesting scenario, because given different circumstances, DDP would definitely be capable of beating up Khamzat.
