In the library scene, Guard Engleheart (Kevin Nash) bends down and says "Bet you'd like to hit us huh?", but the voice is not Nash's deep clear voice. It's clearly the gruff higher voice of Guard Dunham (Steve Austin).
When Crew is stopped by police, he flees the scene. As he leaves the police officers are both shown talking on their portable radios at the same time. Assuming they are partners riding in the same car, they would be operating on the same radio frequency. Thus, they would not both be able to transmit at the same time, because it would just be jumbled garbage to anyone(dispatcher) listening.

Numerous penalties in regulation rules football (i.e. covers almost all areas of football) are committed without being called as such, even after the officials agree to call the game fair. Some examples: -Early in the game, Turley and Crewe help push Megget for a first down. Helping the runner in such a way is a ten yard penalty. -Several players remove their helmets while on the field of play after a down. Unless a timeout has been called or the game stopped for any reason (which it wasn't), this is a fifteen yard unsportsmanlike conduct penalty. -Several violent actions used are fifteen yard personal foul penalties (and probably ejection from the game if done in such a fashion), including punching, drop kicking an opponent, and clotheslining. However, most of these are done for comic effect. -Paul Crewe gives a downed official a "wet willy". Technically, this will get his team a fifteen yard penalty and result in Crewe's ejection from the game.
