I agree with everyone saying Punk not putting over Rock wasn't a big deal. In his promo two weeks ago that everyone creamed themselves over, Punk put himself over Bruno Sammartino, saying he was better because he wrestled and defended his belt more times, regardless of whether it was true or not. Did anyone think he 'buried' Bruno by doing that? No. In fact, we all thought Billy Graham was being over sensitive about complaining about that very thing. People commented that's what made it a great heel promo, the fact that he got under the skin of someone in real life with his comments.
Punk has a record title reign and calls himself the best in the world. It should be expected that he may put himself above everyone else. He's been doing that for quite awhile. It should be no different that he puts himself above The Rock. And to be technical, he never said the Rock was a nobody, just that he wasn't on his level, which isn't the same as saying he was a nobody to beat. Heels are supposed to talk shit, and The Rock is only about the last person in the world who needs a heel putting him over.
As for the promo, I loved it because I loved Punk sitting up in the sky box while Rock was in the ring. I loved the Shield attacking Rock and then Punk getting the last word in while Rock was spitting up blood. It was a great final segment to lead in to their title match on Sunday.
