My experience going through the process with a 2020 is that don't read too much into camp invites. Most are money grabs and are sent out in bulk to players. If a coach is interested, especially with the Sept 1 emails, they will ask for a phone call with your daughter or a specific invite to a Fall Play Day/Overnight visits. I do think Prospect Days were helpful. My daughter selected several schools she was interested in and attended their Prospect Days with interest and offers from each. If your daughter is not committed by November, Presidents Cup is a great Showcase for recruitment. Coach's will come out to see your daughter play if she emails coaches her schedule and they have a need at the position. Good Luck!
