I think the guesses about this group being about guys who couldn't get into TNA are correct.
Let's not forget this video
This was Wes Brisco talking to Kurt Angle. In the middle of the video he asks Kurt if he can put in a word for him about Hogan so that he can get a shot in TNA. I bet you that when he's revealed as one of the members of Aces and Eights he's gonna be pissed that Kurt never did that for him. In this case, it would also make sense that one of the members is Joey Ryan as well. Wouldn't surprise me if we see Kurt vs Brisco at BFG. Personally, I like Brisco minus the stupid tattoos on his leg. There's something very heelish and douche about him which is a good thing.
