Ring of Honor has most of their top guys on short-term contracts now, thanks to the wonderful business sense of Kenny King. I know in recent interviews Kevin Steen had said he'd be open to working with TNA or WWE, but that it'd take a lot of preparation and changes to his life and physique that he'd need to make, and wasn't in a position or desire to do so at the moment. That's kind of ambiguous I realize, but I'd bet a lot of money it won't be him.
Matt Hardy has explicitly said that ROH has him under a contract. So he's not a free agent.
The fact that Dixie came out and used the words "free agent" have me thinking Mike Bennett. His current angle in ROH pains him as a high profile free agent with a lot of offers from other companies. Reports have been everywhere saying he had a tryout with WWE, but it'd be a great catch by TNA if they snapped him up without the internet finding out.
She also said the new person would be joining TNA over the summer; not right away, necessarily. If it were somebody without obligations, you'd think she would use them right away, no? Could be one of the newly released NXT stars. Only Derrick Bateman and Ziggler's brother could maybe be considered "big" free agents; I wouldn't call either of them "big" though.
It's not Batista. He's in London for the next 5 months, and wouldn't even entertain the idea anyways. THere's not enough money in the world. Fancies himself a "WWE guy" through and through. How touching.
It's not RVD. It could be, but they just let him out of his contract. WHy the hell would he resign so quickly?
MVP says it's not him.
Now, with all of those people out of the way, the only free agents currently on the market and operating in the US that I could think of are Bob Holly, John Morrison, Kharma (Awesome Kong) and Carlito.
Holly worked a few One Night Only events for TNA recently, so it's plausible. I still wouldn't call him a "big free agent", and at 50-years-old he's not much of an acquisition.
I would think Kong would go back to WWE if she was fit to work a fulltime schedule again. Reportedly, the door is still open. Also, she frankly said it isn't her.
Fans have wanted Morrison in TNA for years; if it was going to happen, it would have.
Carlito's not contracted to FWE, but he seems happy with his annoying "body guy" douchebag gimmick.
So...who's left? Kelly Kelly? Beth Phoenix? Kelly left to be a model again, and there's no way she'd go to TNA over a WWE return. If she wanted to wrestle, the door is open. SHe's way too much money for TNA anyways.
Now...Beth, is a different story. She'd be the kind of gal that wants to go where the wrestling is. I could very well see her showing up in TNA. And that'd be a hell of an idea. Beth and Mickie, Beth and Velvet or Beth and Gail could be great matches. The Knockouts are getting stale, and Madison is having a baby; they need fresh blood.
To summarize:
It's not...MVP, any top ROH talent, Matt Hardy, Kelly Kelly, Batista, Awesome Kong, Rob Van Dam, or Kid Kash.
It might be...Derrick Batemen, Bob Holly or Beth Phoenix.
It is unlikely to be...Carlito, John Morrison, or CM Punk. Ok, so it's not CM Punk.
