So Seattle is probably the 1 seed in the NFC and everyone knows they have the biggest home field in the NFL, but can't a smart coach easily take that away?
By rule, the NFL is not supposed to allow crowds to dictate games the way they do:
"When, in the judgment of the Referee, the level of crowd noise prevents the offense from hearing its signals, he can institute a series of procedures which can result in a loss of team time outs or a five-yard penalty against the defensive team."
Wouldn't a smart coach be sure to make this a talking point all week leading up to playing Seattle? It would get the media talking about things that would not distract for team from the gameplay and be a great way to potentially get the rule enforced, and if it just makes the crowd louder? The Seahawks just get penalized more. That's certainly what Phil Jackson would do.
