Bogey,
Sorry for the delay in responding. HF encourages kids to speak with coaches as noted above. Brendan or another HF rep speaks with the players (and parents) as a group during an extended break on day one. He highlights the "how to" approach a coach at the appropriate time by a player first (not parent) and encourages kids to seek him or another HF rep if they need help with how to engage a coach or are looking to get an intro to a specific coach.
Every coach is introduced on the field in front of the crowd on an early break at the camp. At Long Island this Summer, there were over 100 coaches present. Each coach's name was read, the Coach then stepped forward on the field and waved or tipped his cap.
HF also provides each player a program with a sizable entry for each Coach. It shows the coach's photo, the school's name and nickname, school colors, some specifics about the school like enrollment and location, etc. The program provides space for players to make notes. On HF day one coaches are typically in full uniform. On day two, many coaches go to more casual team practice wear.
The college coaches are everywhere at HF. On the fields during games, in the dugouts, walking between fields, etc. They expect to and want to be approached.
For a rising (or current) junior, I recommend doing a HF event like HF Sacramento or Long Island in the Summer for a rising Junior or Jupiter in the Fall of a player's Junior year to see how the process unfolds and to begin talking to coaches.
If you have a player who is looking at "academic" / selective schools, HF is an incredible forum for that player to meet coaches, be seen live, see how they compare to other players nationwide, etc.
