Considering the tickets are bought, would it make sense to go, have some fun tailgating, watch the kickoff and then leave before halftime so the 2nd half is played to an empty stadium. It sends two messages:
Bills fans love the Bills
Bills fans will not sit through watching a group of have beens and never weres wearing Bills jersey's. It would certainly be talked about during the game.
I'd do the same but direct tv only cares that I pay on time.
