Watch round 6 again. This was the first point in which Julio stepped up his game. He did well but Sergio would still get the best of him in exchanges. If Jr threw more he'd open himself to get countered easily which means the possibility of him getting KOed goes up. So which would you rather see - Julio getting KOed early or saving enough stamina to outlast and KO the older guy (which nearly happened) in the late rounds?
