Definitely Tyson Kidd, it's a safe bet for whichever match he's in on Superstars is the best match of the week.
Maybe he likes being on NXT helping out the young talent, otherwise I hope someone gets fired for not using that guy at all.
McGillicutty's a little green and has potential, but man, that guy's gold on the mic. He's got a beastly look but needs a character. I still think Drew Mcintyre could be a future ME, yeah his mic skills are questionable but they're better than Orton's, Alex Riley has obvious star power and is still over despite not being used in a year, Justin Gabriel can be the replacement for Jeff Hardy (which they need so badly) and Evan Bourne's the second-best seller they have.
Most underrated is Percy Watson imo, he's an awesome athlete and his character is something that can both get over and be taken seriously. He's got a real future.
