Ken Doane and Johnny Jeter are so far above this gimmick it's not even funny. If Doane had remained in OVW for another year, or even two, he'd still have been only 21 upon his callup. He's the closest thing to a can't miss prospect they have, and he's stuck doing this shit. He's green, but even green he's much much better than some people currently on the active roster (Sylvain, Jordan, Lashley all come to mind). Jeter's always been a good worker, and should have been called up a while ago. He really hit his stride as the dickhead heel this past year, and would easily be able to be a midcard/possible upper mid guy in the vein of Jericho or Christian, but again, he's stuck as a face in the crowd of the Spirit Squad.
The gimmick is fine for Mondo, and even Nemeth. Mitchell has a serious back injury, which is why he doesn't get involved much or at all, so there's no telling what's in his future.
