I think this is a good, solid signing for TNA Wrestling. Not a blockbuster, "will change the world of professional wrestling forever," type of signing, but a good solid addition to the Knockouts division. I really haven't seen her wrestle all that much to be honest, but from what I understand, she's supposed to be pretty good. Plus, because she didn't wrestle extensively while in WWE, she likely won't be labelled a "WWE reject" per se; she will be known likely for her pre-WWE work rather than for what she did in a WWE ring. A good looking woman, sexy as hell, which is pretty much all that matters in women's wrestling nowadays anyway, and that applies to knockouts or divas.
Just keep her away from Paul Burchill, the last thing she needs is to be further associated with very controversial storylines that will kill her career in TNA just the same as it did in WWE. There's no recovery from even the suggestion of such a storyline.
