I'm saying Cena is a better big match player than Jericho, always has been and always will be. Laugh at his number of moves, his technique, his corny shtick, whatever because when the lights are on bright and it is time to deliver he shows up and shows why he is the man and Jericho (many others too) never could be. Cena creates an electric atmosphere and is a showmen which GTS fans hanging on everything much more so than Jericho can ever dream of off his great wrestling. Jerichos best matches have not been versus great grapplers, but they have come from guys who were pure showmen with the lights on and world watching like Rock, HHH, Shawn, and so on.
Do you really doubt that two of the greatest 10 superstars of all time in the company's history (Cena will be there and is there right now hated or not) will be outdone by Jericho and Punk? Do you doubt that Rock who has had classics that will always be remembered of anything jericho has done at his peak with the likes of HhH, Austin, Hogan, Taker, and countless others despite not being technically sound will not bring it? Do you doubt that the Cena who went a hour with HBK, tore houses down with Edge, battled with Dave, and walked into ONS where he was hated and soaked it all up only to deliver will not show up in the biggest match of his career at WrestleMania?
The same can be applied for Taker and HHH as their list of great and memorable matches and moments are piled high in comparison to Jericho when at his peak he was never close and past their peaks, Taker and HHH have routinely been better in big matches than him.
Jericho and Punk should go for a 4 star match IMO. I will not sell Taker, HHH, Rock, or Cena short though as they have always been better than Chris and have always delivered far more under pressure. I think those 4 men will leave far more of themselves in that ring than him, much like they have done for years in the past. Just might be me though
