When Kirk lets go of the motorcycle and it crashes into the garage door the front wheel is on the left, but when shown from the reverse angle the front wheel is still on the left when it should be on the right.
In the final game, after the fumble, the ball is picked up. But in the next shot we see the ball in the lower left corner of the screen bobbling on the ground.
At Danielle's restaurant, the lights that form the shape of a cowboy in the background change from facing the left to facing the right between shots.
As the Highlanders were scoring the touchdown in the state finals, a Highlanders defender #19 was shown shoving a Rocky Creek player #32 in the back while he was already on the ground. It was a personal foul that was way too obvious to be missed, so in reality the touchdown should not have counted.
At the first football game that Gil goes to, the announcers
say that that was the first win since the last Bush was president. Then, when Gil goes into the office and the coach and the principal are thanking him for all he did, the coach then states that it was their first win in five years. The movie was made in 2002 when George W. Bush was president, five years before that Bill Clinton would be president, not George Bush.
The correct name of the disorder is "Tourette's Syndrome", not "Tourette Syndrome", as it is written on the informational sheet the counselor shows Dizzy and his father.
When Dizzy tells the band about getting them a paying gig the day after the football teams first win he says they will be headlining homecoming two weeks from Friday but they play the Championship game before homecoming. If their time line holds true the football team would have only won 2 games before the title game and when has a state championship been played before homecoming
When Dizzy goes to the mall to see his girlfriend in the bikini, the extras in the background are standing still for a second before continuing to walk.
During Gil's speech in front of the flag, the Highlanders' number 19 is a black male, but during the game, you can see the skin between his pads and his helmet is white.
At the end of the film, Kirk says "Would you two get a room?" to Nora and Glen, but you can just about see his face at that moment and his lips aren't moving.
A cameraman is visible in the overhead shot during the "Braveheart" sequence.
Kirk advises Dizzy that a girl will "powerlevel" him, as though it were a beat-down. "Powerlevel" actually refers to a concept in Kirk's beloved EverQuest wherein a higher-level character protects and/or enhances a lower-level character in order to help the lower-level character "level-up" at a faster rate. It is actually something desirable. The New Guy and EverQuest were developed by the same company.
Kirk refers to something being as difficult as "...the fiftieth level of Kunark!". Kunark is a continent in the game EverQuest, to which he's referring. There is no fiftieth level.
