Anyone who thinks a dude with a 6"8 persons reach is "weak" at doing 225 21 times doesnt work out, or has insecurity/projection issues. Long arms = lower reps. Id take a 6"5 21 reps, over a 5"11 31 reps everyday and twice on sunday. And yes traditionally in every sport including the nfl and the combine, players with longer arms due less reps. Are there exceptions? Sure. But disagreeing with that, is just disagreeing for the sake of argument.
