They brought good TV for 4 months, the wrestling and storylines were utter pish. The product they put out now is a lot better than what they were doing for the first 4 months of Hogans arrival.
Well if you don't watch it enough to know who left why are u commenting on it? Back in 2005 TNA would have guys work on a pay per appearance sort of thing. They weren't signed to TNA they could go from TNA to ROH to any other company out there. AJ, Abyss, Daniels, Joe , Shelley, all these guys worked for ROH at the time as well.
I don't doubt for one second Hulk has creative control, he's just not part of the creative team. They'll have a say in what their character does, not much else I would imagine.
So does that make it less impressive because he was doing it 11 years ago. Hogan and ROck had one of the best matches ever but because he was headlining Wrestlemania 11 years earlier does that make the 2002 match shit? Course it doesn't, shit argument.
