Cena + Taker = Match we DON'T want to see... FAIL!
Stop trying to pass it as a general feeling of everybody instead of your opinion.
The Rock was never a great wrestler in the first place. He had a very small move set containing very basic moves but he was able to still get them over because he had excellent ring psychology. He knew how to make a lot out of a little.
So bearing that in mind I'm not terribly concerned about the quality of whatever match he would put on because I don't really think you forget the things that he did.
