He had emailed a few schools back in the spring (who said they would not be at any tournaments, but come to our camp), had been to one camp at a fairly nearby school, and he had been in contact with some other local schools after a PBR showcase. He had some pre-reads underway, with schools who were then at Headfirst. He didn't particularly contact anyone else right before Headfirst.
Headfirst is very well organized, the coaches are really there, in the dugouts and on the field, they really do talk to players (and to each other), and players can make an impression if they do well.
