What we have here is a failure to communicate!
Titles are confusing. It is about what they are going to do or not do for your son that is important. Don't confuse the champion in your son's recruitment for the decision maker in your son's recruitment. It is often two different people. We experienced many different recruiting situations. If you don't know, ask who is making the decision. This is 100% the recruits responsibility.
We experienced coaching confusion at a D1 mid-major. We knew who the champion was. We knew who the decision maker was. But apparently the RC (champion) sent the HC (decision maker) a note with details about my son's visit that he hadn't read. They weren't on the same page, and of course it was the RC's fault (according to the HC) for not following up with the HC. Even when the recruit does all the right things you do things they can turn out wrong. Over communicate! None the less, it turned out well as my son left as he left with an offer from the HC.
The lesson we learned is to never take any recruiting communication for granted. Be crisp, clear and concise. Make sure you know who is making the decision, why and when. If there is any ambiguity, ask for clarification.
Good luck!
