WWE - Shelton Benjamin Question?

WWE does not push a guy based on talent but rather on marketability. That doesn't necessarily mean that the marketable guys are untalented but I'm sure you get my point. To name some other talented superstars apart from Shelton who seem to be going nowhere or backwards: Umaga, John Morrisson, Kozlov, R-Truth, Chavo. Even Kane looks like he's going backwards. And I can't believe WWE let Kenny Dykstra and Elijah Burke go. I really thought that both those guys could be the next big things in the WWE!!!
