Gridiron Gang(2006)

The uplifting story of detention camp probation officer Sean Porter, who creates a high-school-level football team from a ragtag group of dangerous teenage inmates as a means to teach them self-respect and social responsibility. He is joined in this experiment by co-worker, Malcolm Moore. But Porter must first overcome almost universal resistance from the powers that be -- his skeptical bosses and coaches at rival high schools who don't want their players mixing it up with convicted criminals on the football field.
