How much do coaches and admissions people talk?

I would like to weigh on in on this since we were in a similar situation. We had a couple of coaches who were constantly in contact with DC. Also captains of the team. Communications came on a weekly to biweekly basis. DC was waitlisted at those schools. However DC was admitted to schools where he only talked to the coaches 1 to 2 times throughout this process. It was actually a very interesting turn of events. However we are a financial aid family and I believe The financial aid budgets at the schools he was waitlisted at had everything to do with it. So the answer is you just never know.
