Well Jericho isn't the ONLY one who 'gets it'. I'd say that Kane and Big Show are 2 other vets who 'get it'.
As for the Jericho vs Fandango scenario, here's my take:
I don't have a problem with Jericho putting over younger guys. He's help put over Punk last year, then Ziggler. Great stuff. I don't have a problem with Jericho again putting over a younger guy at this years Wrestlemania.
What I do have a problem with is WHO he's putting over this time.
Fandango/Johnny Curtis hasn't done ANYTHING in WWE to deserve being put over by someone of Chris Jericho's calibre at the biggest ppv in the business. I could at a push agree that he deserves this chance at a regular ppv (I say at a push), but at Wrestlemania? No chance.
If you think otherwise, then please, come at me with your reasoning. But Winning season 4 of NXT (Every season of NXT after 2 were a joke), and working in developmental/dark matches for years does not equate to being deserving of a Wrestlemania match against one of the best ever in the wrestling business.
I wish Curtis the best of luck with his new gimmick, I hope it gets him somewhere, but he doesn't deserve this much this early with the gimmick, no chance in Hell in my book.
