The "WWE interested in the Briscoes" rumour has been around for years and years now. Nothing will ever come of it because they'll never pass the medicals.
Bennett is pretty average really and as has been said a million times only stands out because his gimmick is being a "WWE guy" in ROH. He's a cut way below the previous generation of indy guys that signed and I don't think he'd ever amount to anything major because he's got nothing in particular that stands out. It would be good for a laugh if he gets signed though and Maria doesn't, since she's been using him as a way of getting back to WWE since the beginning.
