They dropped the ball with him big time at the end of the Nexus angle. He was outstanding as the leader of Nexus. Garnered more heat than anybody has for a long time.
Poor packaging and booking have been his down fall ever since. It's incredible to say considering how good he was during the Nexus angle, but he's probably never going to reach that level again thanks to Vince and co.
he can never be taken seriously with that joke of a finisher, needs a new finisher asap, imagine him closing out a main event with that move ugh. Also looks like Bo Dallah will be taking the ic belt from him in the near future
