ghoti, thats some very interesting numbers you post there. I say that because I just turned 15 a month ago, and while I haven't been able to get clocked since I turned 15 (also a football player and I've been preparing for season), my numbers from 10-14 pretty much match your son's. While on occasion I hit a little higher (83-84 a few times), for example 80-81 is where I usually topped out (although I would obviously break 80 a few times) in most workouts when I was 14. When I was 13, while I dont remember the exact number, I was throwing in the low-mid 70s. And when I was 12 I was throwing just slightely slower than your son (I seem to remember 65). So I wonder if that means that your son and I will end up throwing with simular velocities?
