Williams was not in shape for the first fight IMO, he looked sluggish half-way through. I think either he completely underestimated Quintana or something. He was looking for other fights, had a long lay off, then fights Quintana who is a difficult style matchup. This time he will have a better gameplan for Quintana and if his stamina doesn't improve the same thing could happen, because Quintana was beating him to the punch all night.
