>>10100325He wasn't over enough for that spot.
Rock/Cena was always going to headline 28. And Punk didn't deserve to be in it at 29 either, no one cared when he was champion for 400 days and it was proven when Rock drew that huge rumble buyrate and the casuals DIDN'T KNOW who Punk was. by the time 30 came he quit because he was even less over than the year before.
