Wisconsinite here, born and bred, but transplanted to Virginia. Question: did any of the Packers refuse to honor the National Anthem?
There was one Bennet brother on the Seahawks who sat during the anthem. Two of his teammates stood, but stood next to him instead of in line with the rest of the team. There was another Bennet brother on the Packers side who stood, but raised his fist in the black power salute during it. Nobody else did anything.
Seahawk Bennet got the wind knocked out of him or something at one point in the game. When the trainers walked him off the field, there was very little applause for him. Usually when an injured player is taken off the field there is polite applause.
