The idiots on the internet bashing Punk saying hes gonna get 'killed', He was trained in Martial arts. Sit the fuck down and fuck off keyboard warriors.
He mentioned in the interview with Dana that he's trained in BJJ on and off. So he hasn't trained consistantly.
If he wasn't famous I doubt Dana would be so enthusiastic to sign him, but he knows that Punk will probably get a few more ppv buys.
