Does anyone know about D3 school timelines? When to contact coaches, send video etc? I'm specifically referring to the top D3 schools. I know there aren't any athletic scholarships, but academics will hopefully be a game changer in tuition.

We have learned so much about D1 but very little about D3, other than a few important showcases and the more we look at schools the more we think D3 will help my son go the furthest academically, athletically and career wise.

Thanks for any input.
