If the Rock were to show up at MITB and cost John Cena the championship. I mean think about it, you could have Rock screw over Cena and Punk take off for a little while with the title. Madden mentioned it in one of his articles. Cena would be fired for a little while preventing any kind of Rock/Cena confrontation, but still adding to the interest in WM next year. Cena could be miraculously rehired in a few weeks the match at Mania would be back on and we would be back to the status quo.
To the mods I know that there is a Rock/Cena thread already but I think this is a novel idea. Won't happen but I think it would work.
Why would the Rock cost Cena the championship when he knows it would get Cena fired and therefore blow his only chance to get his hands on Cena at WrestleMania? Furthermore, why would Rock screw over the WWE by allowing CM Punk to win and leave with the title?
It would be a silly twist to the feud. You say it'll prevent any kind of Rock/Cena confrontation, but I have a better idea on how to prevent any kind of Rock/Cena confrontation. Don't have any.
