Where we live kids transfer schools all the time for athletics. Mostly private school kids but public school kids too. Most times it works out but not always. I have seen kids transfer their senior seasons to play for a particular coach or system for baseball basketball and football. In our conference this summer several schools ,including ours, had starters transfer out to other private schools as well as from private to public.Our Conference does not allow transfers within the conference past Sept of Soph year without sitting out a year.
Some kids already had offers and others were chasing offers by going to programs that have a history of college commits they turn out. Our school wont accept a senior transfer that is from within our general metro area. Some programs are more aggressive than others when it comes to recruiting bona fide D1 players for any sport and they only care about how their program is perceived once they announce publicly how many players sign D1 NLI.
