Let's face it, Miz plateaued a while ago.
That's for sure.....and one of the problems affecting him today is that he reached a level higher than his ring ability and charisma should have taken him. I could never figure out how the company saw Miz as a world champion, fighting evenly with the main event wrestlers in WWE. But once he attained those heights, there was nowhere for him to go but down.
That said, I've enjoyed him a lot more as a face, still using that marvelous speaking ability to antagonize the bad guys and their managers in interviews. Keeping him in a suit is a great idea; he truly seems to bring the best/worst out of his interview subjects by showing them the disgust they merit (that deal with Miz and Paul Heyman the other night was classic.....Miz was more effective in what he
didn't say, yet conveyed with his attitude).
At the same time, why consider retiring Miz as a wrestler? I still think he could lift a few weights and make himself more body-impressive, yet the company can always use a ringside personality who can step in the ring to settle a personal dispute with his fists.....like a younger version of Booker T.
Miz is a better ring worker than he used to be; I would think other performers enjoy working with him because he handles himself smoothly, sells well for others and no one seems to get hurt when tangling with him.
So, no, I don't think he's better off in non-wrestling roles.....he's a wrestler who can talk, so why limit him to the mic? Let him do it all.
