Ziggler should have been the Heyman guy in the Punk feud, not Axel, who's as dull as ditch water in the ring. There's only so far Heyman can elevate a guy like that, but Dolph? Could've done wonders for him.
I still somehow think somebody else will be introduced into the Punk/Heyman feud before it's over. Now that Punk has PROMISED that he will get his hands on Paul Heyman at Night of Champions (which, honestly, is the only thing I could see reasonably selling the PPV at this point, since it looks kinda like a total space filler otherwise), I can see the WWE SWERVING us yet again and introducing a new threat. Not to mention, the Punk/Heyman stuff still gets some of the best ratings on the show, so they'll wanna milk it for all it's worth. (HIAC is a better PPV to pay off such a feud, anyway, since I could see them giving Punk the freedom to actually make such a match look brutal.) I'd prefer Ohno, since he appears to be in better shape, is an excellent worker in the ring, would bring the history (and WWE loves to make Punk's past, kayfabe and not, a part of his storylines, since it draws in the smarks) into the mix, and is old enough that he needs a BIG angle if he's going to make any kind of mark on the main roster, even as a midcarder, but as he appears to still be in the dog house, I don't see that happening, despite how fucking amazing it would be.
What I'm thinking - what I'm HOPING, really - is that Punk actually does start to beat the hell out of Paul Heyman, but somebody runs in (maybe even from the audience) and attacks Punk to save Heyman's skin, hoping to be represented by him and get the "Paul Heyman guy" rub. It'd be great if it were Cesaro, but I don't think there's really room for someone else in the main event scene at this point; regardless, I think The Real Americans is a good place to keep him in a holding pattern until they have something REALLY juicy for him. So who else could they feasibly introduce to keep this story alive?
