If you can not get 12 d1 commits on the field with significant playing time you should not be coaching. If you have 12 d1 commits, you should be able to get 18 players significant playing time even in tight games
I have seen D1 schools play 18-19 players in tight games.
Every coach should have the problem of too many d1 commits.
Problem is high school coaches choose starters and then act like the starter is 10 better than player right under him. Which may be the case- but definitely not all the time- a lot of times there is not much difference.
