the only one that makes sense is Bully Ray to me and the reason for it is the current feud seems to be leading to a Ray and Hogan showdown. now hopefully (if this match does happen), in this match the World title is NOT on the line, in fact, i hope that the title isnt in Bully's hands when they wrestle as i dont even want the threat of Hogan winning a title to happen and also hopefully in this match, Hogan puts Ray over.
I agree, maybe Hogan can screw Bully out of the World title and get fired as TNA GM for unprofessional behavior. Then they wrestle at BFG in a non title grudge match. Then you have to solve the other problem, what's the new World title match for BFG?
It seem a match with Morgan or Bully would be possible based on the TV storylines, but honestly Hogan is no longer a draw, and I doubt TNA get say another 20k buys just because he's wrestling on PPV.
