John Morrison
It really bothers me how no one ever explained that John Morrison left. He was one of my favorite WWE Wrestlers and then suddenly R-Truth messed his knee up and he just disappeared. His WWE contract actually expired right around the time of that whole R-Truth going totally ham story and he went to fight on the international circuit. I think he's fighting under his real name now, and from what Ive heard he actually just recently won an international championship belt in 2013. There are a few rumors out there about him possibly returning to the wwe in late 2013, but with the kind of success hes having he'd probably have better luck just doing what he's doing now. If he does come back I hope he keeps that sick coat that he had before, duster coats are the coolest! xD
Edge
I don't know if it was just me, but when Edge announced his retirement in 2010 I actually felt really sad to see him go. I mean, its hard to believe that such a great WWE legend could be brought down by such an old back injury. Its a real shame that he's gone, but considering how long he was with the WWE I'm not really surprised, it was probably his time to go anyway. Even now I can see the WWE scrambling to fill his place bringing a ton of new wrestlers in in these past few years, but none of them have really stacked up to the real legends of the past so far. Some even only last as long as a couple weeks. Like Kaval, he was only in there for like a month before he disappeared from the ring. There will never be another Edge, and hopefully Christian stops getting in trouble for drugs and switching to TNA. Yeah, I know whats up XD
Kaval
Im going to be honest and say I really liked Kaval. He was a good wrestler and Im kind of a sucker for high flyers xD But he just kept losing all of his matches, even though he actually seemed to have some pretty great potential. I guess he was meant to be somewhat of a replacement for Rey Mysterio, who has kind of been making his way out. I still don't understand why they kicked him off of the roster as fast as they did though, it seems pretty unfair. Id kind of like to see him come back at some point. Maybe hes Sin Cara. Who knows xD
