A request like that is absolutely the best kind. They have seen you play....and obviously liked what they saw. Just keep contacting them weekly like they asked. If he has already given them his schedule, maybe update them each week if he knows he will definitely be starting (or not starting) each game of the weekend. The travel coach would probably change up the starters if a college guy shows up at the game to see your son, but it would be easier if they know ahead of time. If you see the coach at the game....do not tell you son lol. He has enough pressure, doesn't need more. If a college coach is at a game and comes up to introduce himself to you....feel free to talk to him. He can't get into specifics about your son and recruiting, but he can say "Hello, I'm Coach XXXX from Big U State" If that happens, there's a pretty good chance that the interest is real. Good luck
