coaches, though also teachers at the high school, are there before and after school, during the football periods, and obviously long weekends with games, breaking down film of opponents and own team.
The specific compliments my son was getting were specific to technique that he's been taught, so CaliWG has a good point. He'll get a little more athletic, but less coaching upside than kids not receiving the type of individual attention you get by having that kind of coaching staff.
