There's no scripts....
There's mistakes, not scripts. There might be bias at times, but not scripts. Bias and mistakes are the human element. The rules might suck, but it's how the NFL and the competition comittee wants the games called.
The Iron Sheik doesn't play in the NFL. If player drops a pass, missed a tackle, jumps offsides - he gets benched and it's over. An official makes a bad call and it's "Scripted".
If you've never been on the sidelines or in the team bench areas of an NFL game then you don't know. If you have - you'd know it's not scripted.
