I really really hope Henderson signs with UFC again, he could really put a dent in the current LHW standings. I think he really deserves a title shot after his last couple of fights (and after one or two matches with the UFC top LHW's). I love seeing him fight, the guy is a tank and he's seen just about everything and everyone on the mat.
Actually, right now the way he's fighting, I think he can beat Rampage and Machida, and maybe Shogun and Rashad as well. There is no one outside of JJ who has a good chance of beating Hendo. And even Bones, since we haven't seen him defend his title yet, if he regresses and goes into title defense mode instead of "***** this is MY title and I'm going to beat you before you beat me" mode, then Hendo has a good chance against him as well.
