The Longshots

Yahoo Movies:
"Curtis Plummer -- a down-on-his-luck former high school football star -- turns his niece, Jasmine, into the quarterback of the local team, the Minden Browns, and gets his stride back when he becomes the team coach. With Curtis as their new leader and their pigtail-wearing star player, this team of misfits wins its way to the Pop Warner Super Bowl and the small city of Minden, Illinois, is ignited with team spirit, town pride and the glory it once knew."

A formulaic, family flick you won't mind watching with the kids.
