Continuity mistake: When Adam Banks is playing in one of the games, he scores a goal and his teammates on the bench stand up and cheer when he scores. Problem is, Adam Banks is on the bench too.
Continuity mistake: In the championship game, Banks gets knocked out of the game when he is checked into the goal post. If you look at the action after he's gone, you can still see Banks in some of the action. You can't see his face, but you can see his number 99 playing in some scenes.
Continuity mistake: When Charlie is taking the penalty shot in the championship game against the Hawks, you can see his shot is low to the ground but in the very next camera shot it shows that his shot hit the top corner of the net.
Continuity mistake: In the first game against the hawks, they come down on a 4 on 0 and Goldberg says "oh no not again". You can see that the net is new with white netting. However, in the next scene it is old and grey.
Continuity mistake: When Gordon's long-time friend shows him the hockey skates he'd like him to put on, he's holding them with his fingers on the laces and his thumbs underneath. The camera angle changes, and now his thumbs are on the laces with his fingers underneath. It goes back and forth like this several times.
Visible crew/equipment: When they're practising and they leave Goldberg tied up against the goal-post, you can see behind him the reflection of a crew member moving.
Continuity mistake: When Bombay is out of the limo which is on the ice, he is reading his list of players. He says, "Conway, Charlie. Averman, Dave." There was a Dave on the team, but that was not Averman's first name.
Continuity mistake: The flashback in the film's opening sequence shows coach Riley telling Gordon, "If you miss this shot, you're not just letting me down, you're letting your whole team down". Later in the film when this flashback is revisited, Riley now says this sentence in reverse "If you miss this shot, you're not just letting your team down, you're also letting me down too".
Continuity mistake: When Tammy and Tommy first join the team and get their uniforms, Bombay helps Tammy get her shirt over her head. Her hair is tucked in the shirt. In the next shot before she talks to Tommy, her hair is above her shirt.
Factual error: In the beginning of the movie when Gordon Bombay is coaching D-5, there would be no way this team would be permitted to play with the lack of and/or outdated hockey equipment. Goldberg has no goalpads, most of his skaters have no full facial protection, no shin pads and the use of bike and football helmets. From at least 1980 all minor hockey programs required kids to wear full face protection.
Other mistake: In the end credits, Charlie Conway is written as Charlie Conroy, and Larsson as Larson.
Character mistake: During the hockey playoff montage the announcer makes several mistakes with regard to who has the puck and who scores. During the game against the Hornets the announcer says that Averman scored the final goal when it was actually Charlie who scored (if you pause you can see #96 shoot the puck). Then during the game against the Cardinals the announcer says that Averman passed the puck to Banks who passed it to Guy who then scores. When watching the play-by-play again, Guy is actually the one who passes to Averman who then passes it to Banks who scores off the glove tip-in.
Character mistake: During the game against the Cardinals in the playoffs, the announcer says that Averman passed to Guy who then scored. First, Guy does pass the puck back to Averman, but then he passes it to Banks who scores the second goal, propelling them to the playoffs.
Character mistake: When Coach Bombay has the Ducks practice passing eggs to each other, he tells them "Concentration, not strength." At the end of the movie, when the Ducks say goodbye to Bombay, Fulton Reed repeats this advice to Bombay, but he gets it backwards. Fulton says "Remember: strength, not concentration."
