That just shows how terrible the writing is then; use a wrestler to prolong a feud for a manager instead of the other way around.
Further: Axel was immediately buried by Triple H and for some reason did not have him retaliate at all. Then he "beats" them because Triple H collapsed on his own for whatever reason they never disclose, then beats Cena by countout because of interference. Not that Axel ever had much charisma to begin with, he needs helluva lot stronger booking than that to start out. And they failed to do that. Ryback is similar, losing every match against somebody who isn't a complete jobber. Big chance to make him the #2 babyface in the company, and instead turns him heel and he jobs more.
List goes on for people they've made into practically nothing or midcard at best: Barrett, Ziggler, Kofi, Miz (he sucks, but his WWE title reign was ass), ADR, Swagger, Christian since returning, Sandow, and can throw in McIntyre if you want. Basically, if you're not in Evolution, Sheamus, Cena, Bryan, or Roman Reigns, you're pretty much a bug on the windshield.
Ryback got punished for doing the spear and jackhammer in a match when he tried to get WWE to do him vs Goldberg and it wasn't going to happen. They were trying hard to avoid Goldberg chants with him at the time, so it's his own damn fault, even if I'm a fan of the big guy. (Seriously I find him more enjoyable than most of the roster)
As for ADR, he's clearly talented as hell but the fans just didn't take to him for some reason. Sometimes it just happens. I think if WCW was still around he would have done a lot better there- he just screams WCW-style guy.
