I say Roger Mayweather or Floyd Mayweather sr. one of the reasons the looks so good working the pads is because they can keep up with the fighters.
Who held the pads for Camacho and Jones? Merkenson is Jones trainer so he should be mentioned. I beleive old ass Matos was Camacho's trainer, but I don't think he would have had the speed to keep up with Camacho. The same with Merkenson. Maybe it is another team member's job.
I say Roger Mayweather. If you pay attention, he is the fastest one. Floyd Jr most of the time is just going thru the motions. He is not hitting the pads. Is Roger hitting the gloves with his pads
