I know people bemoan TNA's penchant for signing released WWE talent, but all three of these would make good additions to the TNA roster. Helms is a grossly underused but very talented worker with charisma to burn - provided he's playing a heel and not a cheesy superhero babyface.
Burchill got madly over using a gimmick of his own creation, only to have Vince kill it. You're not allowed to get over without his express permission, you see. That said, there may not be room for Burchill in a crowded TNA roster right away. And Haas is a very, very good worker. He rarely got a chance to show it. No charisma, though.
Maria... I just want to plough her. And it's criminal that she's no longer on TV.
