During the final goal-line stand, a close-up is shown on Rudy Zolteck. Junior is standing next to him. When if shifts to Danny only seconds later, Junior is on the bench.
The glass of milk when Danny is talking to the girl.
On the final drive for the Cowboys, they make it to, roughly, the 10 yard line after a long run - gaining a first down. They then only run 2 plays before the ball is turned over. It should have only been 3rd down after they ran their toss (where Spike is tackled inches from the end zone and the ball is turned over).
The clock ticks down from 5 seconds to 4 seconds long after Spike was tackled near the goal line and the whistle blew. There should have been 5 seconds left for the last play.
You do not kick extras points in peewee football as they did in this movie. Nor do you kick field goals.
Danny says a "huddle" is a Latin word for "round". However, the real Latin word for "round" is "circum" where the words "circle", "circus", "circa", "circumference" and "circumstance" stem from.
In football when it is a turnover on downs, the opposing team gets the ball back at the exact location of where the ball ends at the last play. On the Cowboys last possession Spike gets a few inches from the endzone, but when Giants have the ball, they start from the 20-yard line.
When Kevin O'Shea's wife and daughters are watching the home video of his tackle gone awry, what they are watching is obviously from the film, complete with different angles and shots of him from outside. His daughter could not have caught it all with the camcorder.

During the Cowboys last possession when the film is going in slow motion, you hear the quarterback yell "Down... Go!" When the camera pans to his face, it's obvious that he is mouthing "set", not "go".
The movie is set in Ohio, but in numerous scenes, mountains such as those found in California are visible in the background. Ohio does not have any Chaparral-type mountains.
Spike's father says he treasures Kevin O'Shea's football legacy. Yet he doesn't recognize that the O'Shea he's speaking to is not Kevin but his brother, Danny.
When the brothers are racing to get the new player, one gets held up at a railway crossing. The train would hold him up a few minutes, but he should eventually arrive not long after his brother, yet he does not.
In the coffee shop when one of the old timers is writing down the odds on the upcoming game, he writes + 40 points under the Cowboys as they are the heavy favorite to win the game. He should have wrote -40 points. The way he writes it would make the Cowboys the underdog; getting 40 points.
