Triple H injured

Sure, why not? What does it matter if he gets booed in a one-time only dream match. Everyone involved would be too busy counting their money to care about the heel/face fallout from Rock vs Cena.

I think at this point, Cena can only gain fans, not lose them. I mean, he's winning some people over by working hard and busting his ass despite being pretty much the most hated pushed babyface in a long time. On top of that, his fans (yes, women and children) have shown that they'll stick by him no matter how "uncool" portions of the audience try to make him out to be.

Taker/Cena works for me because Cena has shown with the Umaga feud that he does well in the underdog role and he's way in over his head seemingly against a legend like Taker, especially with The Streak. Batista/Taker is kinda intriguing but Batista has lost too much steam at this point.
