One of the reasons to attend a D1 prospect camp is that there are other schools that may be in attendance. Not uncommon for a D1 school to invite other D2s, D3s, NAIA and JUCOs to a camp to help coach up and evaluate the players. For example, the FIU (D1) camp also had Barry (D2), St. Thomas (NAIA) Florida National (NAIA) and ASA (JC). Many times the coaches have great relationships with each other. And while a player may not be opening the eyes of the D1 coaches, it might be a great opportunity to be seen by the other coaches that are there. Might give a player a chance to introduce themselves to a coach from one of the other schools at the very least. Later, after a follow-up email to the coach from the player, the player can attend that particular school's camp with some hope of (maybe) being on the radar. But again, it's extremely helpful to have some dialogue with the coaches before popping up at a camp expecting to get discovered.
