I'm assuming you already sent him the package/letter and called him and his coach already (calling coach shows interest). I would than do a scouting trip followed up by a phone call (to get his thoughts), than another scouting trip to see what else your assistant coach may have missed the first time and also to show more interst from you, than call him a second time and get his thoughts again, than try a home visit (it will depend on how he views your school and your interest in him) and see if he takes it. Than do another follow up phone call. You'll know pretty much at this point whether you have a shot, or should just move on.
