. . . a lot of excellent responses above. I can only add that at this level it's important to many coaches how they see the players handle failures and adversity. Most players at the collegiate level handle it pretty well while a few just never seem to be able to. They way I think my son handled it (and still does) is by fully understanding that he will make mistakes and that every player does, so he just keeps working on the fundamentals, As a Dad, I like to solve problems but found the best thing I could do when son was at college and not performing to his own expectations was to simply empathetically listen to him express disappointments and offer encouragement. The social media we have today seems to make it harder for parents to disengage from their children; as lease for me it seemed that way.
DH is right when he says "He'll figure it out". That's what maturing into good young Man is about. huh?
