Its a shame how universally this notion is shot down, just shows just how badly the McMahons have buried The Miz. He's got less than zero credibility thesedays.
I'm a big Miz fan and I think you're absolutely correct, which pains me a lot.
Hell, I can even see a storyline where his soon to born baby and daughter change his ways, wanting to become a role model and want to teach them the good ways of life so he start to give it all, no cheating this way, to become WWE Champion again so he can show their daughters that hard work can make you accomplish anything, and that storyline would be great and symphatetic with almost everyone, specially for fathers.
But no, he is relegated to Miz TV where he can carry anyone on the mic and then kick his ass so he can carry them in that way too.
EDIT: Also, not only the McMahons don't appreciate him, but Meltzer and Alvarez (which I like) bury him every time possible, so their sheep audience will shit all over Miz because they can't have personal oppinions.
There's fantastic redemption storyline they could work with Miz.
Before they inexplicably had Shane bury the guy he showed so much potential as a babyface. He's got all the passion, and personality, and ability to convey emotion to make a fantastic babyface. But the McMahons hate the guy for whatever reason, he's too talented to be successful in this WWE.
He should be so much more than he is. He's one of the only genuine Pro Wrestlers left. In a World full of spot monkeys who cant do anything else Miz is an actual Pro Wrestler, but he's punished for it.
At this point I just want him to get a feud. Give him anything, something he can work with instead of barely being on TV and having to carry shit like Ciampa and Bayley on the mic when he is on TV.
