Former UFC title challenger Chael Sonnen weighed-in on the situation during an interview with Sports Illustrated:
When I watched Punk train, I liked the way he attacked. I liked how busy he was with his jab, I like that he finished everything with a kick, I like the way he forces the clench and forces guys up against the fence. When he wasn’t attacking, and the guys were coming after him, I thought that it was a case of Punk’s best defense is a good offense. He started with jiu-jitsu, but I’m not certain he wants to go to the ground with Gall. I think Gall wants to be the one to take him there, so I’ll be looking to see if they’re standing up or they’re on the ground. If I were in Punk’s corner, I would feel a little more confident if he were standing. Punk really respects Anthony Pettis, and I know that he watches Pettis spar, and I’d like to see him standing up. That’s where he focused a lot of his attention, and Duke Roufus is such a good coach, and he is a puncher and a kicker. Punk has been one-on-one with Duke Roufus for the last two years—I would like to spend two hours with Roufus—and he knows what’s going on.
I think this is a pretty quick fight. The nerves are going to help lead to that. It’s Punk’s first time out there, and Gall is getting thrown right into a card with a fight for the heavyweight championship of the world, it’s a big deal. That would lend to both guys’ gas tanks emptying a little quicker, and I’ll give you one prediction: this is over in the first round.
