Penn beat himself. He was dominating Hughes until he got tired and then Hughes cruised to an easy TKO, with the way Penn was gassed I think there are people here that could have beat him so I don't buy the "Hughes has heart!" argument unless heart means getting dominated until your opponent gets tired.
GSP is going to beat Hughes. He should have beat him last night.
This December is gonna be an MMA fans dream with Tito/Chuck II, GSP/Hughes II, and Cro-Cop/Fedor II.
