I get what you mean, but these guys are in peak physical form. As a lesser personal example fro
my own collegjant career when I played ball, I was actually faster my junior year weighing an additional 10 lbs than my senior year. I tried to shave some weight and it only brought my mass now, but did not add to my acceleration or top end speed. It’s a lot about body composition. To think he’ll shave 10 lbs and be meaningfully faster is not practical.
