Nearing the end of the second period of Team USA's first game against Iceland, the score is shown at 5-0. Iceland scores one more goal before the period ends. Then at what is intended to be the start of the third period the scoreboard shows the a 4-0 score and that it is the start of the second period. shows a score of 4-0.
During the game where Bombay comes back and apologizes, the team performs the Flying V and the announcer says he has never seen the Flying V before, when in fact he is the same announcer that saw the Flying V during the team's last game in the first movie.
In the game when Ms. MacKay is coaching, they show a shot of the game, and you can clearly see Charlie, Number 96, playing in the game. When they cut back to the bench, Charlie is next to Ms. McKay, telling her how to call a line switch.
In the first game scene against Trinidad and Tobago, the camera pans across the registration area by the ice. We hear the announcer talking about the game, and he says the score is 6-0, but the score board seen above the ice reads 7-0.
When Gordon returns to the Ducks with the duck call, Jesse, Charlie, and Folton are all on the ice preparing for a face off. When called over to the bench, more players appear to have left the bench and gone on the ice.
Right when the camera is zooming in on the Trinidad game you can hear the announcer say the score is "six to nothing" but if you look at the scoreboard, it says seven to nothing. The announcer is actually correct. During the game Team U.S.A. scores three times and the final score is 9-2. If the score had been seven at the start the score would have been 10-2.
When Adam gets injured by Sanderson after scoring in the first game against Iceland, it cuts to the USA bench where the players, including Connie, stand up and complain. In the next shot, she is seen on the ice with Charlie, Guy, and Jesse fighting off Sanderson.
After the press conference, Coach Bombay and Tibbles discuss the Iceland coach. Behind them, Averman and Hall walk off the platform. When Coach Bombay and Tibbles move on, Conway, Gaffney, and Wu move into the same spot and behind them, Averman and Hall walk off the platform again.
Adam says he is from Edina, which is a suburb of Minneapolis. In the first movie, his address is mentioned as 450 N. Hennepin Avenue. In reality, Hennepin Avenue is in Minneapolis proper is does not extend into Edina, so Adam would have to have moved between the two movies for this to make sense. (This is also doubtful, as he is derisively called "cake-eater" in both movies; cake-eater is often used disparagingly in the Twin Cities for residents of the affluent Edina.)
When Fulton is taking his shot in the final shootout, he stops and then shoots the puck. In hockey, you are not allowed to stop while taking a penalty shot and the puck must always be moving forward or else the shot is over.
Icelandic last names are very simple, consisting of the father's name plus either "sson" if the child is a boy, or "dottir" if the child is a girl, but almost none of the Icelandic skaters have last names that could actually exist in the Icelandic language
A few players throughout the movie are shown shooting ambidextrously: meaning they shoot both right-side and left-side. Unlike switch-hitters in baseball hockey players either shoot left-side or right-side, but never both.
During the final game against Iceland, Russ Tyler is being pinned against the boards by three Iceland players. The next shot shows three other players on the open ice, then the three on Russ again. Each team can only have five players on the ice at a time use goalie.
The tournament is double-elimination, and in the finals, Iceland and Team USA have both lost one game. This is a mathematical impossibility, because in double-elimination tournaments, one team going into the finals will always be undefeated (so that the team with one loss will have to beat them twice in order to win the championship).
When Luis Mendoza scores in the last period, after he stops and snowplows the goalie in the face, you can see that his foot is in the crease. If the teams were playing under standard rules the goal wouldn't have counted.
A majority of the in-game penalties were either not properly called or not called at all. For instance, several times the referee says "game misconduct" - but issues a 2 minute penalty rather than the mandatory ejection.
Throughout the sold out game at the Anaheim Pond there are numerous empty seats in the upper level and many cardboard cut-outs in the crowd. They don't move and their faces are pure white, they are very easy to see.
In the shootout scene, with the score 3-3, Adam Banks is closing in on the goalie to make a shot. He makes two dekes and you can see the player go to make a third. He misses bringing the puck back for a third deke, but shoots it in the goal anyway.
Near the end of regulation in the second game against Iceland when Russ Tyler is trying to get the puck and gets ganged up on, you see Fulton take down one of the Iceland players on the ice (Notice the #44 on the jersey). However, right after that seen when Gordon is calling a timeout, Fulton is on the bench without his helmet on.
The goof item below may give away important plot points.
At the end of the third period in the second game against Iceland, Russ Tyler is revealed as the goalie in a switch with Goldberg when he takes off his helmet. However, in youth hockey, regardless of whether in the US or international, he would never have been allowed to take his helmet off on the ice.
