Wade Barrett and the nexus was a really bad one imo. Dude got fired but was never off to even for a week and single handed lay beat every member of nexus and literally buried Barrett under a pile of chairs.
Chris Jericho: "It was Team WWE vs. Team Nexus, and the finish boiled down to [Edge] and [Jericho] in there, but it was Cena against a couple of them. John wanted to do things a certain way and we told him 'you're wrong'. He did it anyways, and it sucked. And then after he came over to us and said 'I should have listened to you, but I wasn't seeing it that way.'"
Edge: "I remember. I was like, fine I'm out of the match by that point."
Chris Jericho: "He wanted to get DDT'd on the floor by Barrett, then kick out and beat them both. And you and I were like, that's the dumbest thing. That's just throwing it away for no reason."
Edge: "They should have gone over because they were so hot."
Chris Jericho: "We were fighting for Barrett to go over. And where's Wade Barrett now?"
Who can forget this? Cena was ddt'd on concrete then beats both guys within about 10 seconds of that happening. shyt was horrendous.
though as far as holding down talent, there have been far worse than cena, hogan holding down the GOAT and HHH burying Booker is far worse than anything cena has done.
