Factual error: About fifteen minutes into the film, Ed Harris is in his home watching film from the previous game. In the background, but purposely featured to make comparisons between Harris' character and former Alabama coach Paul "Bear" Bryant, is a commemorative Bear Bryant Coca-Cola bottle. The bottle commemorates the Bear's then-record 315th career victory as a head coach - a feat accomplished in 1981, five years AFTER the movie's 1976 setting.
Factual error: On the play where the ball is intercepted, the players knee touches the ground. National High School football rules state that when any ball-carrier's knee touches the ground, the play is dead at that spot. The player should not have been able to return the ball for a touchdown. It was either a referee's mistake, or a mistake filming the play, allowing the knee to touch the ground. (00:31:25)
Factual error: Towards the beginning of the movie, when Radio is pushing his cart past the pre-season workouts, the Nike football cleats the team is wearing have the '90's style trim and slim "swoosh" even though the film is set in 1976. The shoe style is very modern. At the time of the movie, Nike used a bulkier shoe with a very large and noticeable "swoosh". At the films setting, Nike was a young company mainly selling in the Northwest U.S. and it's very unlike a school from the South would be able to equip their entire team.
Factual error: After Coach Jones takes Radio home for the first time Radio goes into his room and begins taking apart the desk radio that Coach Honeycutt gave him. He takes the back cover off which separates the AC terminals of the radio from the case. This is not a battery powered radio, yet Radio is able to turn it on and we hear the radio operating and the stations changing as he adjusts the dial. If you look closely at the back of the radio in one scene you can even see the AC terminals.Robert Sullinger
