We all knew from the get go this was just a publicity stunt to get the word out there, get WWE fans to tune in maybe or keep an eye on the UFC, steal some of their fans, those Punk fanatics. And then after 1-2 years of training you can feed this fake fighter to some other n00b with 2-3 fights under his belt or something and build this Punk thing up and have a lot of people tune in to a shitty fight and make a lot of money with it because face it, people want to see Punk. Either fail or win. Mostly fail. Well, 90% of them want to see him fail and get his ass beat. But they'll tune in regardless.
Brock was a different story altogether, the guy is a world class wrestler, he's a giant, strong as fuck and extremely quick, tremendous athlete. Punk is an actor. An out of shape actor. He's just a brand, a walking name.
