The Ducks that appeared in the first film but did not return for this sequel are; Dave Karp (Aaron Schwartz), Peter Mark (J.D. Daniels), Terry Hall (Jussie Smollett}, Tammy Duncan (Jane Plank), and Tommy Duncan (Danny Tamberelli).
When Dwayne Robertson was introduced, he says, "It's a great day for hockey." That was a tribute to former Pittsburgh Penguins/Calgary Flames/Wisconsin University Badgers coach and Former USA Hockey executive, "Badger" Bob Johnson, who died in 1991, shortly after coaching the Pittsburgh Penguins to their first Stanley Cup Championship and before he was to coach Team USA in the 1991 Canada Cup Tournament. That was how Johnson greeted his players every day.
The scene after the first game with Iceland where Coach Bombay makes the team do sprints is based on Herb Brooks' 1980 US Olympic team when they tied the Norwegian national team in an exhibition game. The team skated for about an hour even though the rink manager had turned the lights off.
