I'm afraid your right. Punk involved in Cena/Rock would ruin Mania for me at least. The mania main event needs to be one on one always. Look at Mania 2000.
Also, you only water down Rocks star power by putting more people in his matches. That's why they didn't do the Series Elimination match but only a normal tag match at Survivor Series. And that's why they do Rock/Punk in a singles and not put Rock in the Rumble nor the chamber.
The boxing example soneone brought up pretty much nails it.
