It's refreshing to watch everybody grapple with the nuances of basic physics principles, only to discover they don't understand them so well.
1) was the same pressure gauge used for both measurement? If not, who calibrated the precision instruments used by the referees?
2) 1 ATM = about 14.7 PSI at STP. Where was it the patriots were playing?
3) 1 ATM = about 14.7 PSI at STP. These balls were inflated to 27.2 PSI with a properly calibrated pressure gauge, otherwise the quarterbacks are grappling flopping pigskins.
4) height above MSL (mean sea level) also affects the gas chemistry, and gas mixture does drastically impact pressure. Inflating tires with (relatively) inert nitrogen is now all the rage. What if somebody was inspired to use a unconventional mixture?
It's terrific that people are trying hard to puzzle out the mechanics. Perhaps some trust will come out of this with future climate change discussions.
