Let's just pretend Cesaro is this unfairly held down talent who could be a super duper star, but the McMahons and evil Kevin Dunn hate him because he's Swiss. Not that they see him as a solid hand in the mid card who can reliably fill 10-15 minutes of TV with a solid enough match, but can't cut promos and has terrible to non-existent character work for his entire career. I'm sure he'd have so much more luck on Smackdown, where it looks like he's going to need a character and promo work even more than on Raw.
It's definitely not his fault he hasn't worked on the two most important things you need to have in WWE. People seem to forget that he was hired not because he was an indie darling putting on 5 star matches, but because he was twice as big as everyone on the indies. He's been on TV for 4 years, still has no character or promo skills whatsoever. He got in the door because he was big, looked good, and was competent in the ring, with the obvious implication that he'd pick up the promo stuff along the way. Which he hasn't. Which is why it doesn't matter what show he's on: He's mid card for life. And now he cuts quasi shoot promos about how he resents having to work on his promos. In the one company in the world where being able to cut promos is more important than anywhere else.
