Probably a very stupid question for those who have been there and done that. But, for those totally new to the process, this discussion may be helpful.
Coach tells the kid: We really want you to play for us. It's going to cost you XX per year to attend our school. But, I can give you XX dollars the first year and then we can see after that. Depending on your grades when the time comes, maybe I can get you some academic money too. Take your time and think it over. But we hope you can not make us wait too long. We really want you to be part of our program here.
Kid thinks it over. He's already aware that the school is a good fit for him. He decides that he wants to commit.
What should happen next? Kid tells coach he accepts the offer and and then declares his commitment on social media? Is that it?
