SHANE TO TNA?!?!? COME...ON!!!!
Look - I bet you growing up Shane probably enjoyed the business, but knew it wasn't for him. He probably seen shit that us fans would literally pay thousands of dollars to hear about. The wildest stories possible. The craziest shit never spoken about. The downfalls, and the coverups, and how death is treated, all all that shit.
If ie's like most kids, he probably took mental and physical notes of what his daddy (Vince) was doing and what he would'wouldn't do if he could ever run a business of his own. We did a report on this for my capstone in college - the WWE is a dying product and shareholders are feeling it. Its clearly isn't going away anytime soon, but, the cash cow ain't skirting out milk
For all we know, Shame's real passion might be....theatre production. Or, he might have a strong international background. Or,

, he might be a master chef and realizes that he's 30+ years old and haven't started on his dreams yet.
Either that....or like others suggested....he realized that if he stayed, he wouldn't get the business anyways. There's a possibity that all his ideas he had got shot down and he's just not into this business anymore. Lord knows hes not dumb! He ain't going ot show up on TNA or ROH or whatever trying to start a feud that America doesn't care about. And with his background, the public will believe his fights are fixed if he takes over MMA company
Basicaly, this long rant is implying that he's probably burnt out from WWE and just wanna do his thing. If the storylines are right, he probably is more like his mama and would rather be far away from the product. You could always tell Linda was uncomfortable
