I am not counting NXT releases, because they are not known stars.
But TNA is overdue to sign a former WWE star.
angle, hardy, hogan, flair, foley,van dam, booker t, mr kennedy,bubba ray, christian, r truth, nash, hall, xpac, lashley, rhino, taz etc.
have all made there rounds at TNA.
rey, morrison, mvp, jericho, debiase jr, Jim Ross ,???...perhaps a return of christian......
There are a lot of former WWE divas available Kelly Kelly, Melina, Beth Phoenix etc.
The above would make the most sense. But maybe a surprise??...your thoughts.
