01. Samoa Joe
It was no easy task compiling this list. No Bully Ray, no Matt Morgan, no AJ Styles - but we feel that the final man WWE should absolutely sign is Samoa Joe. If handled correctly Samoa Joe is a wrecking machine and it's no secret that he has support from high places including Punk, Stonecold, Bryan and even John Cena. Can you imagine a three way feud with Punk and D-Bryan? Or how about keeping him undefeated for a year and then facing the Undertaker only to loose but look a million dollars? WWE doesn't like to use existing gimmicks a lot of the time but Joe's one of those guys you just can't repackage - and let's face it, he wouldn't be leaving TNA looking all that great.
Opponents of choice: No question: CM Punk and Daniel Bryan. A feud with John Cena would be different for the number 1 guy in WWE too.
