You're not even thinking the right way. If Rock would of lost to Cena, it would been a disaster for the WWE since his fanbase is what has been carrying the WWE SOLELY over the last year and a half now. The numbers don't lie. He was behind the sell outs, pushing Raws to near 4s, and it was the booking and wanting Cena to be perceived a certain way that destroyed all of that and now they can't even get a 3.0 consistently after one of their most watched WMs in history.
People do NOT care about Cena like that. They don't care about Blandy like that. When Punk isn't screaming and whining in his little shoots, he doesn't matter to the overall picture. It's a numbers game. Rock and Lesnar draw....the current disaster can't even get a 3.5 rating if they tried their absolute best. That's why the Part timers SHOULD go over and better go over because the lame ducks of today aren't getting it done.
