Corrected entry: Even if the Warden could frame Crewe for the murder of Caretaker for not throwing the game, the Warden has no jurisdiction on what sentence Crewe would serve or how long, so his threat of 25 years in prison is pointless.
Corrected entry: In the scene where the cons score their first touchdown after Crewe returns to the game, the entire team except for the center line up to the left. In reality, at all levels of football, the center must be surrounded on the line on both sides by at least two players (a guard and a tackle) - the play would be an illegal formation.
Corrected entry: An umpire does not announce penalties in a game. The responsibility actually lies with a referee. In the movie, the mistake is probably made to move the plot forward so Crewe could throw the football twice on the umpire's groin as a way of forcing the umpire to call a fair game.
Corrected entry: There are only two busses leaving the prison - the fancy one for the guards and the crappy one for the inmates - but at the game we see all the good behavior cons and the "cheerleaders". There is no way they all fit on that one bus.
Corrected entry: At the end, when Adam Sandler is walking towards the gate out of the football field and the warden is telling the guard to shoot him, two shots show there is no football on the ground. Sandler then picks the football up off the ground from in front of the left side of the gate.
Corrected entry: On the inmates' first offensive play at the start of the football game, Turley aka "Sasquatch" has long black sleeves like an UnderArmour turf shirt. A few shots later, the team huddles on the sideline and Turley is no longer has the sleeves. Anyone that has played football knows how hard it is to remove the shoulder pads and pro-style jersey like the team is wearing. There is simply not enough time in between these two shots for Turley to remove his jersey, shoulder pads, and turf shirt, and then put his jersey and shoulder pads back on.
Corrected entry: Care Taker gives Nelly a pair of cleats he sneaks into the prison, the cleats are black. But in the scene where they play against the guards he is wearing red cleats.
