Rebound (2005) on Netflix

Coach Roy once was college basketball's top mastermind. But lately his attentions have been on his next endorsements, not on his next game. What¹s more, Roy's temper has run amuck, leading to his being banned from college ball until he can demonstrate compliance--in other words, not explode every time he walks onto the court. Roy waits and waits; for a suitable coaching offer, but he receives only one: the Mount Vernon Junior High School Smelters basketball squad. Roy reluctantly accepts the offer, hoping that a few weeks at the school will prove his good intentions and restore him to his high-living ways as a celebrated college coach. But when old school meets middle school, Coach Roy doesn't know what hit him. It's not until Roy decides to teach his young charges some new concepts--like passing, rebounding, dribbling, and scoring--that the Smelters begin to find success and Roy finds something long thought lost: his love of the game.
