NESCAC Football Recruiting

Seeking advice for D3 and NESCAC football recruiting for my 2023 son. He has three football offers, one from a NESCAC school, one he has declined. So he had two remaining offers, coaches have told him he could decide either ED1 or ED2. How does the later ED2 deadline affect recruiting? He is still in communication with other coaches as well, one of whom have indicated that he may get an ED2 offer. Wondering how many of the NESCAC schools are done by ED1 round in filling up their roster?
