After you’ve been able to connect on the phone with a few coaches, you should not be afraid to bring up the prospect of coming out to a junior day if they haven’t brought it up yet. You’re actually going to be making a coach’s job easier by reminding them they need to get warm talented bodies out to their recruiting events.
Coach, not sure if you might be open to it or not but my folks and I would love to stop by for a junior day if you had one coming up in the next few weeks or months. Thanks! - FIRST NAME
