BaseballDad72, for the reasons that Chico Escuela and Anotherparent say, I think the next six weeks will be even crazier than November to December. Most HA D3s have an early decision deadline of Nov. 1 or Nov. 15, and will need/want to have their offers with admissions support accepted by then. So, there will be a scramble up to that November deadline for the recruits still on their boards before those recruits commit elsewhere. Most coaches will advise that they cannot (or cannot be sure they can) offer admissions support if your son waits to apply regular decision. If possible, your son definitely wants to be one of the offers for early decision admissions support.
Congratulations on getting interest! There are many here who can offer advice and share their experiences as you navigate the next six weeks. Good luck and keep us posted!
