How about a HS sports movie about a real HS sports team....
... that is, not a super team put together through recruiting (DeLaSalle), transfer and consolidation students (Friday Night Lights and Remember the Titans) -- a team made up of only kids from the school's home district, not hotshots who transferred in??
"Hoosiers" would probably be the closest thing to it, but even in "Hoosiers" there was plenty of talk about players transferring in or out.
