One that I'd love to see that has never happened on a big stage, and has never really happened (meaning a match that means anything), is Benoit vs. Mysterio. Why they've never had a long term program, I'll never know. They had a pretty solid match on an episode of SD once (and even that was way back in 2002), have been in a few three-ways together, and have been in tags, but they've never really been in a program together, not even in WCW.
I wouldn't even mind seeing those two feuding over the world title (yes, I said it).
I think their matches would be far better than the Guerrero/Mysterio series.
Am I alone here?
I know it's mentioned before, but never a thread talking about it really, unless I totally missed it.
