First of all, there's nothing wrong with having a man crush on Jericho. I'm definitely not into the twig and berries, but if I were swinging from that side of the tree, I'd definitely swing in his direction. Jericho is a freakin' stud.
Onto the topic now. A Cena heel turn has been suggested to Vince for a long time and he has refused to listen to the idea because Cena is as much of a financial machine as WWE itself. Reports recently have stated that McMahon has become more open to the idea. I don't think it's any coincidence that McMahon's become more open to the idea around the same time that HHH took over creative. Paul definitely knows the value that a heel turn can have appertaining to ratings. While WWE would lose significant revenue from children as a result, I'm sure there are plenty of adolecents and adults who might get behind the turn and help make up for that revenue. The Orton face turn has been surprisingly good so far, in my opinion. A Cena heel turn may possess the same surprising value.
