Cena is the most over rated, no one comes close.
To get back on topic though, I really hope they do not force Mistico to change his style too much. I don't think everyone has to wrestle the WWE style. Those who have wrestled elsewhere, Mexico, Japan, ROH...etc, are usually the ones who put on the best matches. I would take a Punk, Danielson, Mistico, Christain, Del Rio, LowKi...etc, people who have worked many different styles over someone who has just wrestled for the WWE(or OVW when WWE had them) or FCW- such as Cena, Orton and a few others
