I saw a film a while ago, it was about a college basketball team in which the students were allowed to play. They're new teacher wanted the students to earn respect and attend classes. Until this the students basketball matches are cancelled. The parents of the students petition against the ban and they overrule the teacher but the students have other ideas and in the next scene are sitting in the school gym and respect the teachers demands

Coach Carter.. that movie was about a high school team but it fits the description
