Hogan has built up such a horrible reputation over his wrestling career, stepping on everyone's toes to feed his ego. Would he help the WWE? Of course. Would everyone hate him and would there be a lot of heat backstage? Absolutely. It just wouldn't work out. Let him rot in TNA.
That's completely irrelevant to whether or not Vince would want to sign him to a WWE legends deal if the opportunity was present. In fact basing what you "read and hear" about in regards to Hogan's backstage reputation I am sure has some merit, after all people with star power usually have egos but let's not put Hogan into an exclusive group here because he's far from the only one that you could put into that category guys like Bret Hart, Steve Austin, Shawn Michaels, Ric Flair and even The Rock have commanded high prices in the past and with guys like Steve Austin it's also been reported on the net at several times in the past that because of ego clashing certain plans have not gone through (i.e. not wrestling Brock Lesnar, not working Taboo Tuesday 2005 and so on) so let's not base Hogan not getting a WWE legends contract on his ego alone because that's just oversimplifying things.
In fact for all we know that legends deal with WWE might already been signed and established, if memory serves me right he's in WWE All-Stars and even happens to be one of the superstars on the cover of the game. Two years ago he was also in the WWE Legends Of WrestleMania video game as well, and also one of the superstars on the cover of it I might add. It's also worth mentioning that he has made appearances in other WWE media over the years like the Mr. Perfect Retrospective from 2008 (which yes I know predates his TNA arrival but still he was in it) and the True Story Of WrestleMania Blu-Ray, which could also pre-date his TNA signing...however WWE these days ALWAYS timestamps archived footage. So it's possible that despite his status on the TNA roster there could still be some deal in place where he has a loose affiliation with WWE.
Now I am willing to admit that his footage from The True Story Of WrestleMania might have already been in the can BUT I'm willing to entertain the possibility that such is not necessarily the case. If he's being featured in video games as recent as this year then I don't see why there isn't a possibility that Hogan did not sit down with WWE to do the WrestleMania documentary. Again, no timestamp leads me to think of that being a possibility.
Therefore maybe the question should be is Hogan under a WWE Legends contract and not so much if he has signed one. However I'll also field that question because after all that's what this topic is about.
If Hogan doesn't actually have a WWE Legends deal then all the power to him to sign one if possible. If he's in the position to get one no harm, no foul...for people that feel threatened by such a prospect because they don't like Hogan, tough shit for them. Again, just because we read something on the internet does not make us an expert on anything regarding what business decisions WWE and Hulk Hogan should make between one another. Those that think that way obviously must be people that attribute everything wrong with pro wrestling to be in the hands of Hulk Hogan...that's all too laughable. There's money to still be made with Hulk Hogan and WWE wouldn't pass that up because they have shown in the past with efforts like WWE All Stars that they still hold Hogan in some regard, period.
So yes, no one here is disputing that Hulk Hogan has an ego but that just happens to be the case with a lot of people who rake in lots of dough particularly athletes and entertainers but obviously if Hogan's ego was that bad then projects like WWE All Stars, Legends Of WrestleMania and so on would have gone on without him, obviously the man must have some sense of negotiation or compromise or else we'd see very little of him in these said projects.
Jack-Hammer's points are valid and have merit even if I don't agree with everything he says (although I have to tell you Jack-Hammer I think Hogan Knows Best was playing up kayfabe more than anything with the way Hogan and Vince were "arguing" not to say that there weren't ever issues regarding pay with them two but again it's a reality show and it's one about a wrestler...I just can't help but wonder how much of that was actually legit.)
sTyLnK if you dislike or hate Hogan that's cool, it's not my job to convince you to be a mark for him like I am, again I admit I'm a Hogan fan, guilty as charged and what have you. Even if I wasn't a fan of Hulk Hogan, I would still have to acquiesce that him being signed to a WWE Legends deal would only benefit both parties. But by reading your post I can tell you are someone that puts anything about ego and negativity with wrestling on Hogan's shoulders when that in no way can be true. Again when you involve something that makes oodles and oodles of profit you're bound to get more than one ego...period.
