So if your Bryan/Cesaro/Sandow/Rollins of this world were to get released tomorrow from the WWE, you don't think TNA should sign them purely because they are seen as WWE or to some extent ROH guys? It just blows my mind that you would write off a whole pool of talent just because they worked for the WWE. Just because they've signed some trash ex-wwe guys like The Nasty Boys, Orlando Jordan, Matt Hardy, Sean Morley, Ken Anderson etc it doesn't mean they shouldn't pick up guys like Christian, Angle and even your women like Tara and Mickie.
For me, you just have to make sure that those signings don't overshadow your talent you already have that on the roster that are in a similar position to them. Sting needed to be used sporadically and as an attraction similar to how Taker is used although they could probably get more out of him on a regular basis. Hogan should still be the big boss, but in more of a Vince role where he appears here and there for the big angles and big decisions. Angle & Jeff, while they been seen as WWE guys (even though Angle has spent more time in TNA) can bring credibility to the main event scene. Take someone like Magnus for example, he's going to be getting a rub by working alongside Angle & Sting, two bonafide stars and multiple time world champions. You take an upcoming heel for example, maybe someone like Roode or Aries and them going over Angle, Sting or Jeff is huge and would actually make them legit, whereas if you didn't have those guys around in the company they'd have to be going over the likes of AJ & Joe who just don't have the appeal, name value and all that jazz.
I just think in the end up from my perspective at least that signing ex-WWE guys is perfectly fine so long as they still offer something and are booked well.
