Dolph will get back over. He's too good not to.
Fact - wearing the title different, having different coloured merch etc etc are all attempts to get himself over in a different way to people that have come before him. I respect that. He's really what Zack Ryder could have been - in touch with the IWC, in touch with the comedic side of his game and in touch with a new modern era. Dolph knows what's NEXT in entertainment better than most of the top superstars do.
Fact - they won't know whether he can draw until he's given a legitimate chance. Did you hear his cash-in pop? Yeah, I get it, that crowd was smarky as hell but did Punk get ridiculous ovations EVERYWHERE he went during his WWE summer of Punk? Hell no. Bryan's the only guy getting consistent pops. In fact lately he's been put on the card in places it's been impossible to get a crowd reaction because they've been worn out or dead from previous matches - see: vs Dean Ambrose.
I think Ziggler can draw and I think he WILL draw. The guys who have a mind for the business and who have paid their dues like Ziggler has will get over eventually. I don't think with a guy like Ziggler, Vince would give up on trying to get him over. If Ryback is going through every opportunity to reinvent himself and get over then Ziggler will get more chances. The crowd determines who of the smaller physiques gets over and the wrestling cities LOVE Ziggler. That will mean a lot to management.
