TNA originals have NOT taken a backseat to ex-WWE talent. Chris Sabin is a 4x X-division champ, Lethal has been given a new gimmick that has catapulted his popularity through the roof, and "Wildcat" Chris Harris is now in the ME scene. Joe is one of, if not the most over man on the TNA roster, and AJ Styles has held more TNA championships than anyone in TNA history.
Besides, Angle isn't really a double champion. The IWGP title that he struts around with was actually vacated when Lesnar's NJPW contract ended while he was champ and he refused to have a non-contracted match to drop it. NJPW had a new belt created and ended recognition of the belt that Angle now holds, so, conclusively, Angle isn't really getting the "double champ" push you think he is.
Btw, ikdevil, is it too much to ask for you to use correct English? I know the internet isn't all that strict about grammar and that shit but your grammar skills are just sad.
