If your boy is a swarming fighter than he must fight like a swarming fighter. He must get up in on him and just throw punches. Bully him. Del Valle is 42 years old. He can't keep up a modest pace. Much less a good, fast one. If your boy can keep up a fast pace than he'll be alright. Del Valle has never been stopped before. So hopefully your boy stamina is good. Cuz it's going to be an all nighter. Del Valle knows how to fight. His body just can't keep up any more. He'll be a threat for the first 2 rounds than he's done if the pace is fast. Your boy weak chin is a concern. But Del Valle ain't scored a stoppage in about 6 years. So unless your boy's chin is A Mere Con like he should be able to handle Lou's shots.
