I am not sure if anyone else mentioned this, and since I am currently ambivalent to CM Punk (as I once was with Cena, though I am now a Cena supporter) I want to throw it out there.
MAYBE the idea behind giving CM Punk the World Heavyweight Title isn't designed or intended to draw with him as champion at all. Maybe it's designed to affirm to the fans, once again, than professional wrestling isn't as stale or predictable as it had been for some time. That people should want to tune in, because if you don't you might miss something unique or historical.
I mean, who saw Punk beating Edge? Who saw Punk doing ANYTHING with MITB? I sure didn't! And I tune in each week in large part to see how things work out for him. Besides, someone has to take Kennedy's place as cusp main eventer doomed to fail because of overheightened expectations!
