Sponge, I'm not Brock fan but I think he has a legit chance in this fight. For one, I don't think the subs are a worry. He learned in his loss to Mir, he'll stay low in the guard and control the lower body and never have any worries. The question is whether or not he can get close to JDS. IMO if he does JDS will be going down. We've seen it over and over again with the elite wrestlers. I think Cain and Carwin were both bad match ups for Brock because of their wrestling ability combined with their striking. If I was Brock I would do nothing but shoot in for the tds at all cost. If he gets tagged by JDS then he's done. He has no chance if he tries to stand at any point, no matter how much he works on his striking.
I hope JDS wins so we can see him vs Cain because I think that could be a 5 round war.(Cain winning IMO)
