De La Hoya's legs would probably completely gone, he's already too hesitant to pull the trigger, and the snap in his punches is gone. On top of that, Chavez Jr., as sloppy as he is, would use his size and high activity to overwhelm De La Hoya, whose chin would probably hold out for a prolonged beating. It wouldn't be vicious, but it would be consistent, and Oscar would just fade down the stretch. He's just too old to pull the trigger and move defensively against any fighter with a half-decent offense.
