I honestly don't see much coming from Dolph Ziggler to be honest. They need to play up on his gimmick a little, he's sort of a narcissist character at the moment, so they need to play up on it, have him say a few more words than "Hey I'm Dolph Ziggler." Have him tell us why we should give a crap what his name is.
Secondly, really, what's with the name? Dolph Ziggler doesn't sound the name of a guy who is gonna go very far. Sounds like a comedic jobber's name in my opinion. I say call him by his name Nic Nemeth or whatever he's called, it sounds more serious.
RAW needs a some more mid-card names, since right now all we have right now is Kofi Kingston, CM Punk, Miz, and Morrison who are actually entertaining. We need more young up and comers who can put on decent matches, so far Ziggler proved he can put on a decent match. Give him some more TV time both in the ring and out of the ring, and see where it goes. At this point though, he's kinda getting lost on RAW. I don't see him on ECW though, he doesn't look like he'd fit in for some reason.
