Hopefully this will shed some light on the athlete being recruited, the LOA process and more. I just went through this with my son and not for football. First of all you still have to have the grades and go through the process. The coach had our sons SAT score, high school records, letters of recomendation and more, ahead of time, so the coach knew he could qualifiy academcally.
Here is what happened when he was recruited. He went to West Point for a two day overnight as dictated by the NCAA rules. We took tours he stayed with two different players, went to class, went to a football game, went to a game in his sport, we met with the coach, thought it over for a week and he committed to play at West Point
All things being equal, it probably does help being a recruited athlete. The director of intercollegiate athletics for West Point sends a letter to the Senators and Congressman telling them this is a recruited athlete. The athlete still has to complete all the essays, physicals etc. He received his LOA first couple of days of November, then took physical assessment test and received nomination third week of November. Just now waiting for the brown envelope. Hope this helps.
