In the literal sense, a "WWE reject" would be someone who was release from WWE because they did not have an interest in them. If someone was released due to a wellness issue I don't think that would fall under the "reject" category. You would have to define a reject as someone who WWE considered talentless or not worth their time, not someone who was release due to business or legal reasons.
Kurt Angle: I'm sure he would be welcomed back to WWE. Also, I don't think it was ever truly revealed under what terms he left WWE. They surely did not simply release him.
Not a reject.
Daivari: Was offered a new WWE contract when his was up and chose to go to TNA. Clearly that cannot be defined as a reject. Not a reject.
Mick Foley: Chose to leave WWE. I'm not sure what his contact situation was or if he was offered a new one, but it seems likely that he would have a job in WWE if he wanted one. Not a reject.
Booker T: Released supposedly due to wellness issues. Prominently features on TV prior to release and was a former champion. I'm sure WWE would re-sign Booker as well. Due to his release as a result of wellness issues as well as all his successes even up to the time of release...cannot be considered a reject. Not a reject.
Scott Steiner: I have no idea what Steiner contract situation with WWE was in the past. It seems likely though that if they wanted him he would have gone there. Steiner is a shell of himself and really can't do that much. He is a name but based on recent history he's likely to be classified as a reject. Reject.
BG James & Kip James: It was reported that WWE had some interest in bringing them back to TV a few years ago in a role with DX. They were part of one of the most popular factions and tag teams of all time. However, I doubt WWE would have much interest in them at this point. Rejects.
Bobby Lashley: Clearly not a reject. Chose to leave WWE and came to terms with a release. WWE did not want to release him and pushed him very heavily. Not a reject.
Christy Hemme: Winner of $250,000 diva search. Was a featured WWE Diva in Playboy. Was not offered a new contract at the same price. Was not released. It seems that Christy simply did not re-sign a new contract with WWE and I have a feeling she would be welcomed back as well. This is up in the air. If she was not offered a contact I suppose you can classify her as a reject, however, if she simply chose not to re-sign but was offered a new contract you cannot call her a reject. Depends on the story.
"Dr." Stevie Richards: Released by WWE. Did not do anything all that important in his run. Was not a very big name in WWE, most of his success came in old ECW. Reject.
Kevin Nash: As far as I know, was not release, just did not sign a new contract. He is a well known name from the most popular era in wrestling history. I can see that some people call him a reject because of his age and current in ring ability. However, it was reported a few years ago (and constantly) that WWE was interested in him. It was also reported that he was a guest of Vince McMahons at Wrestlemania and is very good friends with HHH. If he wanted to go back to WWE I'm sure he would have a job there...whether it's in ring or not is anyones guess. Not a reject.
Matt Morgan: Release by WWE. Didn't do much while he was there. I thin there is potential in Morgan but based on current definitions you would have to classify him as a reject. Reject.
Rhino: Release by WWE for conduct. I would guess that they would be willing to bring him back and that he could make more money with WWE. However, the fact that they have not brought him back and the fact that he was not all that important in WWE would classify him as a reject. Reject.
Team 3D: I really can't decide what to put here. They are incredible stale, but are one of the most well known and decorated tag teams in history. Supposedly they were offered contracts with WWE a few times while at TNA, though that it hard to believe since there really is no tag team division or push. They are names. I would be willing to accept it either way reject or no reject.
Jeff Jarrett: Who knows with this one. There is a personally history between him and Vince, and it's been rumored that he was blackballed from ever being in WWE again. Other than personal reason I don;t think there are any other reasons he would NOT be wanted by WWE. Due to the fact that he is not in WWE due to PERSONAL reason you can not classify him as a reject.
Elijah Burke: I happen to think Burke has a lot of potential. I don't know why he was released by WWE. But the fact that he was released and did not do anything that big in his time there would have to classify him as a reject. He's young enough that he could overcome this and become a star, and I think he will if TNA uses him right. But for now as much as I hate to say it, you have to say...reject.
Taz: Since Taz isn't an in ring performer I don think you can hold him to the same criteria. He is unable to wrestle and I don't know what his negotiations with WWE were. It seems he walked away, but who knows. Because he is not a wrestler I don't think you need to include him.
Sting: Sting has never wrestled in WWE but many people call him a "reject" when they actually probably mean something like "over the hill." He is very well known, and was one of the faces of WCW at the height of the Monday Night Wars. Has repeatedly turns down WWE offers. You better believe that WWE would be interested in signing Sting even if it was for one Wrestlemania match again Shawn Michaels or something. You cannot call him a reject.
Oddly enough, Ken Kennedy/Anderson who people used to be big on would have to be considered a "reject" if/when he signs with TNA. Umaga, however would not, as WWE still wanted him but released him due to other reasons.
Also, if Jeff Hardy were to sign with TNA he would not be a reject. I personally think it's very unlikely that he would re-sign with TNA, but if he does, he would be doing so on his own accord, after being a multi-time champion and getting a huge push. If he leaves and goes to TNA it's his choice. Clearly could not be a reject.
