My 2019 OF (September 1 of Junior HS Year) received a few e-mails advising him that he was being "recruited." All 3 schools he had prior contact with. No phone calls or text messages for him. Basically, the Sept 1 date was a dud.
His phone/e-mail didn't go crazy with coaches contacting until after his area code tryout 10 months later. As we left the field in Santa Barbara and were driving home, he received multiple text messages, 3 direct phone calls, and later on some e-mails. September 1 is worth waiting for for some who will get a lot of activity. If you don't, I wouldn't be that concerned - just stay proactive.
