There were a lot of kids who could really swing the bat.
There were a lot of "athletes", big kids with speed.
The coaches were extremely engaged, very active and pro-active in the recruiting process. They were there to find and engage players, hunting players down to talk after seeing them perform.
The baseball Heaven facility is very nice.
For a pitcher (my son attended as a pitcher only) the event afforded tremendous exposure, and the layout of the diamonds and advanced posting of game schedules/pitching rotations seemed to make it extremely easy for a large amount of coaches to rotate among fields and see every pitcher they wanted to.
I cannot stress how highly I would recommend a HeadFirst event for any solid HS player who meets their niche target market: Solidly-skilled players (do not need to be a superstar), who are high achieving academically, who are targeting mainly D3 opportunities.
