You need to get them to visit right after a soft commit. You can continue to recruit them until you are blue in the face, but I have only gotten guys to change their mind once they visit. If you used up your visit you might as well pack it in unless the school they soft committed to did not offer a scholarship (that happened to a couple of guys for me). Then continue to recruit them and you can get them in week one of the off season recruiting during the in home visit.
