road games can change the football psi due to the difference in atmospheric pressure. If the Pats fill there balls at Gillette Statium to a set psi where the atmospheric pressure is 14.7 psi and travel to Denver where the atmospheric pressure is 12 psi those footballs will have a lower psi then what was set at Gillette. The same analogy applies when scuba diving where if you fill and tie off a balloon underwater say 60 ft, the pressure will be high in the balloon and when allowed to float to the surface the balloon will get bigger with less pressure inside
just food for thought.

Did a simple ideal gas law calculation (PV=nRT). As shown by another guy up above, you need for the field temperature to be around
10 below zero to get pressures in the range of 1.5 psi lower, assuming the balls were inflated at room temperature. The game
temperature was around 45 degrees. At that temperature, there should have been less than .5 psi difference. Sorry, Bill, no way the
atmospheric temperature makes that kind of a difference.
