I'd maybe take Abyss, Drew, Ec3, Decay, The Wolves, Storm and the Hardy's. I'd maybe take Grado and stick him on NXT where his gimmick might have a chance to flourish and he could team up with Noam and maybe Drew and do some sort of Scottish connection thing and see how that takes off. I honestly don't see them taking on a lot of TNA talent long term, maybe a couple fo the tag team division, some for NXT and maybe one or two making an appearance on the main shows.
I;m sure that this is more about WWE shoring up wrestling history so they have the tape libraries for the network and can now say what they like about any talent who happen to have been TNA employees previously. It gives Drew a little something since he;s obviously been world champ there which might give him the leg up to make a return to the main roster.
