Agree with PG stopwatch stuff is tough. I think obviously velocities are what they are not too tough for a parent to take those. But timing is hard. I just go by what the football coaches get for the 40. I figure if his 40 time is improving so will his home to first and 60 time. Cause for him being a big guy its mostly about the start and getting all that mass going. Track season starts in a week and a half. He will go work out with sprinters to work on his starts. While he won't run in meets should help him for both baseball and football.
