Dumbest thing was I had someone complain that entering the NZ is not a dead ball encroachment foul (Federation rules). This guy is thinking NCAA and NFL style live ball foul. I told him that it was a dead ball foul and he said that it must have been a new rule. I told him it was changed for the 1975 season. I'm not sure if that is correct but that is what it says on this website.
