If the cold weather had such a disasterous influence on the ball pressure, what about all those driving to the game on pressure-monitored tires? Was every car tire suddenly underinflated, or just the footballs?
Cold weather does not have a “disastrous influence” on footballs. Science teaches us that the air pressure is dependent on temperature. If you go from a warm locker room to the cold outdoors air pressure will decrease. Most cars are parked outside or in unheated garages during the winter. Tire pressure is not effected. However, when the weather gets cold tire pressure decreases. I bring my car in to have the tire pressure adjusted every late November or early December.
