Your son needs to be a starter next year and show well. Not playing varsity as a sophomore is understandable when Kendall Milton is the guy ahead of you but next year he needs to be the guy and have good stats/film. If that doesn’t work out you can still make things happen as a senior but you’re playing from behind and essentially trying to backdoor your way into a signing class where the coaches struck out on whoever they were going for first (someone who had good jr film). Or they’re trying to get you as a preferred walk on.
He’s also got 2 good summers to go to BYU football camp and that will help a lot.
