Miz, Sheamus, Rhodes and Ziggler. Miz is sadly the only redeeming one of the group, the others are completely dull and lifeless and boring beyond belief, just the way Vince likes 'em. I'm not really including Del Rio since he's only gonna be around 5 years. A long time, to be sure, but his push will slow down in about 2 years. Great talent, though. I'd rather he stay over the rest of these drones. Mason Ryan is also a possibility just because Vince loves talentless dickheads with muscles.
If it were up to me, I'd push Alex Riley and Wade Barrett to the top, but WWE won't do that. They have no future.
The next 10 years are looking bleak.
