The problem with that idea is that you're forced into having a draw or some other non-finish. Danielson, as ROH Champion, isn't about to lose on a PPV, and Daniels isn't about to lose a non-title match to someone who isn't sticking around. And even if Danielson did come in to TNA for a while, he isn't going to do jobs while still ROH Champion.
I'm completely aware of that, I'm just saying Dragon would be the closest realistic name to matching Liger to the market they were looking to attract.
