I don't know how passionate Punk really is about this stuff, but if he really wants to stick with it, maybe it's better for him to not be on big PPV slots anymore. Not only does it turn UFC fans off to see a "draw" take up a spot on one of their bigger shows, when a more talented fighter could be taking that position but it's also sad to look at honestly. In WWE, there's no problem in putting a draw first, given that they can make him/her look strong in their own way, but here it's just like putting a celeb in there just for some publicity instead of a competitive fight.
I wish him the best and hope to one day see him catch a W in this sport but I'd also understand if he stops now before he gets seriously hurt
