If it was a D3 LAC, I’d think the coach has little to say about it. Coaches can’t give out scholarships and can’t tell the FA office what to do. And the coach can’t know if the NPC was filled out correctly, if all the assets were included, if the parents knew to add back in the 401k contributions.
I’m not saying that schools do not look at the NPCs that you saved and reconsider the FA, but earlier this year a parent posted that U of San Francisco’s award wasn’t close, and they did say “Sorry, that happens sometimes.”
