I am looking for an older football movie title. The only thing I can remember is a coach takes his team in the boonies to train on a dirt pad and toward the end they become good and the other coach has stolen their play-book. Any ideas?

Sounds like "the Waterboy" with Adam Sandler, Jerry Reed, and Henry Winkler, just to name a few

Little giants

1st hald sounds like The Junction Boys. Not sure about a stolen playbook though.
