I'll add one more thought. After attending a the PG showcase in June my son got ranked as the #14 SS in the state. After that emailed all the 50 coaches on his list with the subject line "#14 ranked SS the State." He got a good amount of replies and I think the ranking helped him get the coaches to watch his videos and make contact with him.
The interesting thing is he ended up committing to a school that he never emailed or sent a single video. They saw him play live 2x (one at a PG event) which goes back to my earlier post on the thread. You have to get in front of coaches and play.
