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."
