I dont think BJ would want to fight sherk again or at least any time soon. BJ only wants the big fights now and it would be hard to get fans to think Sherk would have chance to beat him after there first fight.
I am a Fan of Sherk, but BJ v Sherk 2, wouldn't interest me at all now. I know its a little early to say this, but i dont think Sherk can cut it with the top LW's any more. Sherk/KenFlo 2 Would be a better fight but i dont see Sherk winning.
