Why isn't there? EVERYONE has tapped to it. Edge, Sabu, Triple H, Kurt Angle - there's simply no reason to believe that RVD wouldn't tap to it.
If they wanted to make it good for both sides, they would have done it, like the guy above me said, when both men were down. They clearly booked it to make it look like Cena had RVD finished if it wasn't for Edge. Which is pretty much the same thing that happened at ONS. They could have at least thrown RVD a bone and had him about to finish off Cena before Edge comes in.
