Dolph Ziggler- Honestly, I would love to change this guys name to something more believable. What the hell is a Dolph? And what the hell is a Ziggler? Maybe go back to some of his old ring names.
Changed to-Nick Nemeth
Dolph was supposedly inspired by the actor Dolph Lundgren, who played the Russian Ivan Drago in one of the Rocky films (I can never remember which one) and Ziggler was inspired by Nemeth's German heritage, as Nemeth is a common German surname. He chose it because he thought It'd stand out, and to be fair, it does.
Michael McGillicutty is the obvious one that springs to mind. It does annoy me that when WWE has an opportunity to capitalise on the fact that a legend like Mr Perfect has a son on the roster, they decide to give him one of the worst ring names in the business. FFS [B/just let the man be Joe Hennig[/B], and get The Fortunate Sons teaming together to boost the tag-team ranks.
Also, I really am not a fan of some of the awful ring names that alot of the FCW guys use. I would have Seth Rollins go back to using Tyler Black, Kassius Ohno revert back to Chris Hero and I would have brought up Antonio Cesaro under his original ring name of Claudio Castagnoli.
I don't know about Truth or Bourne, but I do know that Henning chose the name McGillicutty himself so he wouldn't be stuck being known solely as the son of Mr. Perfect. Sadly for him that backfired in the beginning, as everyone referenced him as Curt's son, but now I think hes doing well by himself, especially on NXT. He's easily one of the top guys on the show and he's constantly improving, plus Triple H is pretty high on him.
And on Black, Hero and Castagnoli. I don't know about Castagnoli, but before signing for WWE Chris Hero promoted his final independent appearance and said it would be the final time people saw "Chris Hero." It was his decision to use the name Kassius Ohno.
One thing to remember when these guys sign for WWE and are given these names, is they benefit from it. When CM Punk signed for WWE he refused to sign over his ring name, then last year as his contract ticked away reports surfaced he had signed over his ring name to WWE. Which means, if CM Punk left WWE tomorrow and went back to the indies, much like The Dudley's can't use that name anymore and had to go as Team 3D, CM Punk couldn't be used.
WWE want to own all intellectual property of their talent for marketing, likeness rights and such, so for that reason its better for guys like Hero, Castagnoli and Black to use other names. If they return to the indies in a couple years time or whenever, they can return being known for what they were, instead of Black going under the name Colby Lopez, or Hero as Chris Spadlin.
