According to PWI, only a few names would work with the stip of having the title in all the company's worked for.
Flair, Hogan, Hart, Sting, Angle, Nash, Savage, The Rock, Jericho, Booker, Big Show, Sid Vicious, and... wait for this folks.... Goldberg baby!!! Benoit was on that list as well but yeah.
We can effectively rule Sting, Nash, and Angle out (don't ask me how I know).
Flair is still under contract with WWE and has said emphatically he wasn't going to ever go to TNA.
Hogan would probably not mind helping TNA out at this point, but I believe that WWE Hall of Famers and WWE Legend contract holders, of which Hogan is both, have to have all appearances approved. Don't think Vinny's going to approve that one.
As much as it pains me to see my hero in the state that he is, Bret just can't go. That kick to the face ended his career for real. We're not talking HBK/Charles Barkley/Roger Clemens type of retirements, but the real deal. He's done forever as a wrestler which is sad really.
Rock or Jericho would instantly sit me in front of my TV every thursday night, but I am sure Jericho is behind the cryptic save_us videos meaning he is back under contract and Rock just really truly seems done.
That leaves us with Savage, Booker, Big Show, Sid Vicious, and Goldberg.
Randy is a psycho and though a Poffo-Lethal feud or tag-team would be sweet, I doubt they want to deal with the headache Mach brings to a company, though they might for the "draw" even if he isn't that much of one anymore.
Everyone has outlined Book and Show so I'll leave that one alone, though either would be interesting, just not going to be sure to draw me every thursday with either of these guys.
I recently was surprised at an indy event when they announced the main event was a local vs Psycho Sid himself. Sid looked REALLY good and could still get it done in the ring. In fact, it was one of the better matches I've seen in a long time. I'm sure he'd want to get back on the big stage, just as Jericho said. I would love to see Sid on television though.
That leaves us with the name of the hour in this post... Mr. Goldberg would be sa-weet! I would be plopped on my couch instantly... I mean I DVR all the shows anyway, but they just might pull me in live if Goldylocks showed up, as long as he goes all old-school, just saying who's next so I can mark out like a twelve year old Cena fan.
True story. Long post but I thought I'd throw in my fifteen cents worth.
