The problem with the suggestion of Riley is this: It would be somewhat of a step backwards for Miz. He took out Morrison, who though he hasn't been active lately, had a really nice run within WWE, including winning two titles alongside the Miz. He and Truth were main-eventing shows and main evented Survivor Series together. So his attack on Truth had impact as well, because Truth is relevant and has been for some six months now. While attacking Riley wouldn't be a terrible waste, devoting time/energy to even a segment where Miz does so would be a waste. He needs to keep climbing the ladder in terms of relevance with those he attacks.
For reasons already mentioned, attacking Cole would be a terrible idea. Cole was to Miz what JR was to Austin for a period of time, and again, think big picture. Does him attacking and starting a feud with an
announcer that people hate anyway benefit him whatsoever? No, it's a large step backwards. With WWE clearly going somewhere with this angle, including devoting main event time to it two weeks ago, it clearly is going to be a big story. Getting sidetracked with Riley or Cole isn't the answer here.
To me, the next logical step is Cena. Granted, CM Punk is without a challenger at TLC, and they conveniently got ADr'S rematch out of the way on Raw instead of saving it until TLC, which just so happens to coincide with the time Miz is getting his renewed push. it's not a coincidence, but I still feel like Miz has some unfinished business with Cena. However, Miz feuding with and losing to Cena at TLC would be damaging, so I'm going to say for argument's sake that he and Cena have concluded their business, and he's off to CM Punk, who he'll challenge for the title in two weeks at TLC. Too soon? Perhaps. But who's really left for Miz to attack and climb the ladder by doing so? There's really only Cena and Punk left, and Cena is dealing with issues of his own, and will probably destroy whomever he faces next due to the "pressure" he's under. That leaves Punk, in which likely will be a fairly long feud.
I think Miz will attack whoever, not sure any of the victims need to "make sense." This is leading to a Miz/CM Punk feud, I think. Not sure how long it will last, probably not through Mania, but I'm guessing around Royal Rumble time, we'll be seeing a Miz/CM Punk title match.
I respectfully disagree, and agree at the same time. I do believe this is leading to a Miz/Punk feud, but I do believe that the attacks from here on out need to make sense. With them devoting segment/match time to these the past two weeks, it's obviously they're pushing this angle hard. In order to present Miz as a serious challenger again, he needs to continue to attack people that are relevant, Sure, the random backstage attack on a Riley wouldn't be a bad thing, but it doesn't position Miz as a main eventer either. He needs a logical progression up the ladder, so I do believe the attacks need to make sense just in the sheer idea that he's working his way up.
