Chicago Reader review:
George Roy Hill's usual spit-and-polish direction makes a fairly funny film out of the story of a bankrupt minor-league hockey team saved from the brink when the coach (Paul Newman) discovers the drawing power of unbridled violence. The film strains a bit, getting some of its biggest laughs out of the savagery it's trying to condemn, but Nancy Dowd's script embodies the best (worst?) of jock talk, and the supporting cast contributes some fine caricatures (1977).
Here (and above) is the trailer.
