Many college coaches are away for the summer doing various recruiting projects and/or running camps. I would email or call directly. Many programs, even ones that appear to be good programs, have part-time coaches who do not work at the school over the summer months. Sometimes the online recruiting forms may not be sending the information correctly to the coach. If all that fails, it may say something about the coach him/herself or the program in general. It may say that the coach really isn't interested.
