He's never been a Big Name in WWEs eyes though. Best use for him at this point would probably be tag teaming with jericho again.
I always said Christian screwed Christian. It took years of failed tried and leeching off other names to get him over. Edge, DDP, Trish, Unamericans, Alliance turn, Jericho, a bodyguard ... They tried it all and he finally got over. Then he left them high and dry. He left them high and totally dry and sd was in dire need of talent when they lost Eddie and others around the time. He screwed Vince, and Vince ain't forgiving or forgetting totally since he isn't a money maker like Hogan or Brock. Vince didnt discard him like Kurt or Jeff (the first time) he got jilted by an ungrateful bastard he wasted years on and never got to cash in on when he was finally building steam
His ceiling has always been that of IC champ or ECW headliner, not world or wwe title material, as we all know that reign was because of Edge, a true star.
