The kids on the hockey team -- as well as the hockey coach -- learn the values of teamwork, good sportsmanship, and playing a sport for the fun of it rather than winning at all costs.
Some body-checking in hockey games, some light wrestling and shoving. A boy is knocked unconscious during a game by being shoved from behind and sliding headfirst into a goalpost. In an alley, kids get into a shoving match that is broken up when a much bigger boy shows up and throws the three bullies who started it.
Kids find a box of Sports Illustrated swimsuit issues in a Dumpster and proceed to rifle through the issues while yelling excitedly. A lawyer brags about how he "scored with the court reporter."
Occasional swearing from kids as well as their new hockey coach in front of the kids: "bastards," "pissed," "hell," "suck," "weird-ass," "bitch," "damn." In an obvious double entendre, a science teacher asks a group of kids studying the figure representing a molecule, "What are the blue balls?" A boy tells another boy, "Why don't you play with yourself?"
Early in the movie, a character is shown drinking and driving. He is pulled over and arrested for DUI.
