‘The NFL does not have a league-mandated dress code. It lets its teams institute their own policies, and Buffalo’s is as follows: On travel days to road games players must wear sport coats and dress slacks from their homes until they arrive at the team hotel. Once they are in the hotel, they can wear whatever they want. On game day, they must wear similar apparel from the hotel to the stadium, and then from the stadium back to the airport for the trip home to Buffalo. For home games, there is no dress code.’
