RVD doing Indys would suit him. He'd barely have to work more than a couple of days a week and they would let him choof as much as he wants. Match made in heaven tbh.
Hope TNA can find a few more guys to add depth to their roster but part of me feels they need to have a breakthrough star of their own, not just grabbing all of WWE's free agents to really elevate their brand. If they can show that they're the place to be for good entertainment and a fresh style of pro wrestling they could be a threat.
Atm they still seem sort of second tier to most casuals, and hoovering up all the guys deemed not good enough for WWE doesn't do them too many favours. They aren't really differentiating their product from Vince's.
I think this is true, but I think there are some exceptions to this. Lashley may have quit the E, but I think he has spent enough time away from the business, that if he were to return and make it big, he could be categorised as a TNA star rather than a failed WWE guy. Kennedy perhaps less so, but arguably he could go the same way.
I think it would be very hard for TNA to make a star completely off their own bat so to speak. Obviously AJ, Samoa Joe and Kazarian are all what most people would call proper TNA raised stars, but outside of the IWC they aren't really given any recognition, I think in order for them to ever make it big they need the ex WWE guys to help put them over to an extent. Tbh I'm not really a fan of any of those three, I think they are all ok, but not as special as the IWC fanboys would have you believe. In some ways I really regret Christian coming back to the WWE, as watching TNA now, you kind of realise how much they miss him. I sympathise with TNA using older talent which are effectively WWE cast offs, as I think to a point it is a good way to help establish your own credibility, however, like you say, there is a very fine line between doing this and just being seen to clear up the E's scraps and repackage them, and I'm not quite sure which side of the line they are on at the moment.
Also I think in terms of different their product from Vince's, less would be more in some instances, I mean, when the TNA management tries to hard to be different, it often has an adverse affect (can't stand the king of the mountain matches, and not that keen on ultimate X either), obvoiusly you need to be different to some degree, but there is a reason why Vince's formula is so successful, and so it would be stupid to try and be a polar opposite.
