Well he better shorten up the move set a little more and make it a little more basic since he did get hurt doing a hiptoss......
Cena is crap, for numerous reasons. His moves and same old stuff over and over again are obviously a reason. His promos suck too, people think he's good on the mic, and sure he has charisma, but his promos are the same thing over and over and over and over again. It's always about overcoming the odds.
Orton and Michaels are way better than Cena will ever be.
I'm still waiting to see the figures for the merchandising stuff, but even if Cena does sell more, that in no way relates to him being a good wrestler.
