Yes - If He Can Develop A Persona & Connection With Fans.
That's the poll answer most folks have chosen. It's certainly a hopeful outlook and it would be nice to see someone like Cesaro achieve it, but I don't know how he's going to pull it off.
They've tried it before.....and it didn't work. Don't tell me they didn't try to push him as a singles competitor. They gave him a good chance and he simply didn't make it; not because his ring work wasn't up to par, but because he was trying to force upon us a personality that just wasn't his. If the powers-that-be can find a way to make Cesaro dynamic on the mic, then they can probably move mountains and control the planet's weather, too. I mean.....really.
Sometimes, the writers can tailor a persona for a wrestler....but mostly, they can't. An example of "can't" is Cesaro's own partner. Jack Swagger is a guy they tried like hell to push to the moon, even giving him a world championship very early in his career. After that bit the earth, they took Jack off the air and brought him back a long time later, pushed him....and it again didn't work.
On the other side of the coin is Daniel Bryan. Despite the fact people are going insane for him today, he wasn't always in that position, was he? He was doing his fair share of jobbing early in his WWE tenure. Yes, he always had the technical excellence, but that wasn't translating into career success when they had him sacrificing himself to push Sin Cara, was it? But in his case, Creative found a way to get it done, casting him as the lovable underdog.
Honestly, I don't see Cesaro as that kind of character.....and given the blandness of his personality, it doesn't appear that his latest push is going to amount to any more than did his first.
I'd love to be wrong on this. Cesaro's strength is in his ring work....and if they can find a way to get folks behind him with that, maybe this ca work, after all.
