He didn't win anyone over...the kids were finally heard and that was a bunch of kick outs in that $hit too. Same $hit people cried about during the Rock/Cena II match.Rock is great. No doubt about it.
But to knock Cenas in ring ability is just stupid. I can hate the character and still objectively enjoy his matches.
Watch the MITB 11 match with Punk again. Not only is it a WRESTLING CLINIC ( ironically the only noticable botch was punks fault) but even that CHICAGO crowd was cheering for Cena by the end of the match. He won them over, relatively, with his work.
CM Punk/Bryan at Over the Limit actually WRESTLED and without the bull$hit drama of no selling to give Cena the big comeback.

now. That match and the 1 hr match on raw was never terrible
