Koufax said:Russell Wilson took his helmet off. Why were the Pats penalized but not the Seahawks?
Wilson taking his helmet off wasn't a penalty. It has to be part of a celebration, demonstration, or confrontation.
R12, S3, A1(h):
(h) Removal of his helmet by a player in the field of play or the end zone during a celebration or demonstration, or during a confrontation with a game official or any other player.
