I also believe JJ would have been a great choice but considering his last appearance in the company it could be awkward for some casual fans. I'm not sure who should be next, but they have plenty of great choices down the line. It should be a yearly thing, but with only one person a year like this first one.
Down the line in the future? Jeff Jarrett, Raven, Abyss, Jerry Lynn, Ron The Truth Killings, AJ Styles, Daniels, Samoa Joe, Sabin, Chris Harris, BG James, Kurt Angle, Team 3D, Storm and Roode for what they have done in tag team, god knows the sky is the limit for the rest of their single careers.
Knockouts? Def. Gail Kim and Awesome Kong, Angelina Love too.
Non wrestlers include Jerry Jarrett, James Mitchell, Tenay, Hebner, maybe even Cornette and Dusty Rhodes. Eric Bischoff, Scott D'Amore, Borash, Lee South, Hogan, Russo, Dixie Carter.
Some of these names should only be included after an expansion to the system and the number of entrants being inducted. I can't imagine a whole year towards some of these, but they have earned their spot in some way. I'm sure TNA's list of inductees will stand legit in the long run. No former rapists or actors for marketing and promotion. God knows Mayweather might make that hall of fame in the future.
