since you didn't seem to understand, your statement was stupid because it had no bearing on the conversation. Try to defend you position.
LOL.
Moving the goalposts refers to changing the rules to put you at a disadvantage once a previous standard has been established. That extends to calling infractions differently or consistently which in effect is changing the rules. The roughing the QB change would apply until it becomes understood as the new norm.
Here's another definition:
move the goalposts
If someone moves the goalposts, they change the rules or aims in a situation or activity, in order to gain an advantage and to make things more difficult for the other people involved. He was always moving the goalposts so that we could never anticipate what he wanted. They seem to move the goalposts every time I meet the required conditions. Note: You can also say that someone shifts the goalposts. The administration is shifting the goalposts and changing its demands.
By being inconsistent in their calls or by simply changing the circumstances of making the calls, like that for roughing the QB, the refs and NFL are in effect 'moving the goalposts' when players and fans feel they meeting the conditions of the rule. Refs determining the outcome of a game, as the OP suggests, means they have done precisely that, otherwise the players and teams would be determining the outcome with the refs being consistent in their actions within the margin of error.
Now pull your boxers out of your crack or I'll get Remy to help me.
