Thanks (again) to all--this has been helpful.
Did any of you find the PG Academic showcase helpful? We are in NC and most schools my son is interested in is are in the northeast or mid-Atlantic. His summer team will play in the WWBA in July and he is signed up for Showball academic in mid-July, but otherwise he's not likely to be seen by any schools outside the southeast. The PG Academic in in mid-June this year in Alabama. Did any of your sons attend that? Were HA coaches actually there or were data from the event useful? (Son already has a PG profile that shows him well, but those numbers are from 2018.) Coaches from some schools have texted / emailed just to say "keep me posted" and son has sent his spring and summer schedule to ~25 schools. So they know where to find him, but they aren't typically in our neck of the woods.
Any other recommendations for showcases (other than Headfirst and Showball) that get a lot of HA schools--especially ones that are fairly early in the summer?
