I'd suspect Porter if he can get inside. It'd be an extremely rough fight and someone's getting KO'd.
Huge fan of both. Watching both fight I have to go with Keith. People claiming his suspect chin would get him floored DKSAB. Dude is incredibly talented, and I think he definitely has the skill set to get away from the inside fight of porter
Thurman would move on the back foot and counter Porter until he fell. he wouldn't let Porter get set, or let him on the inside. Thurman by late stoppage.
