As for the fight itself, it was a decent one. Hall slowed down considerably after the first couple minutes. I don't think he was tired, but rather Adam caught him a few times pretty cleanly which seemed to make him fight a bit more conservatively. I also don't know what the hell Adam was doing just standing there like that before the KO. For a guy that'd been moving around fairly well for the first 4:50 of the round, coming to a sudden halt for seemingly no good reason is an odd tactical choice.
