At first i thought Jeff Jarrett would be behind Sting's attack and would have been the leader of this stable. But now that it seems that they will be some what of a bikers stable, it doesn't seem as likely as before. So with that being said, the possible leader of this stable is now vacant with only a hand full of guys that i can see filling out that spot
Kevin Nash - Has expressed interest in going back to TNA & he has a motive to go after Sting and Hulk Hogan, having worked with them both in the past while in TNA
Goldberg - Just fits the biker gimmick pretty well and will being a ratings mover for TNA
No One - They can just end up turning out to be guys who are blaming Sting & Hulk Hogan for not getting a contract with TNA and are getting their revenge on the Hogan, Sting, and the rest of the company
Hmmm Goldberg is a keen biker, Batista also seems to like bikes, both teased big announcements this year on their twitter accounts, but I think Batista's announcement was that he was starring in that film, only Goldberg could be said to have a big grudge against Hogan and Sting? But Goldberg also said on his twitter that he'd never work for TNA and was going on about facing Brock Lesnar at Wrestlemania.
LOL WWE has already shown they are not interested in Goldberg, when the rumour was that Goldberg was interested in WM 27 in Atlanta. He is not exactly Rock or Lesnar when it comes to popularity, he is an old news.. So he can dream, but there is no chance in hell WWE would waste BROOCCK LEEESSZNARR (in heyman's voice) and his limited dates on Goldberg, esp after their shitty encounter at WM XX.
