I have to wonder what on earth John Laurinaitis did wrong. OK, I know he was fake "fired" as GM but ever since, his role in the company has been diminished. Now, reportedly, he's a road agent - quite a come down from VP of talent relations.
I can't help but speculate if Johnny Ace has fallen victim to Vince's fragile ego. It appears to me that Laurinaitis, much the same as Jim Ross has had the rug pulled out from under him and I suspect for the same reason this fate has befallen each guy because they were doing their job too well. Is Vince threatened by people who are more in touch with the business than him? More over than him? Of course this is speculation, but it's my best guess.
Of course, they might have simply pissed Vince off in some other way. Or it could be the old 'team underperforming, sack the coach' routine.
