Corrected entry: The Warden recruits Crewe to get an inmate team together that will give his guard team some good practice with tough competition before the season starts, but when the Mean Machine plays well and starts to win he orders Crewe to throw the game and let the guards win in a cake walk.
Corrected entry: When the score is 8-0 guards, the cons score and go for two and get the two-point conversion. However, the scoreboard shows a score of 8-7 and this is also announced by the radio announcer. It is never corrected as more points are added. The score should have been 8-8.
Correction: Until recently, the conversions were 1 point no matter what. Since this takes place in the 70's, the score is correct.
Then why did the guards have 8?
The guards scored a touchdown and had the extra point blocked. Then they got a safety. That's 8.
The guards scored 2 on a safety.
Safety= 2 points.
While the NFL adopted the 2-point conversion in 1994, the 2-point conversion has been around long before that, and throughout the 70's. College football adopted the 2-point conversion in 1958. The AFL used the 2-point conversion in the 60's prior to the NFL/AFL merger. In the film, it was a semi-pro team and they could have chosen to adopt the 2-point conversion.
Correction: Because they had a score, missed conversion and a safety.
Correction: This is the plot of the movie, not a plot hole.
