(I suppose NEXT you will be using your “physics apologia” to try to convince Us that the Patriot sideline was 20 to 30 degrees colder than the Colts sideline)
Nope.
The Colts’ footballs would have been affected exactly the same amount. But if the loss of pressure was 1 psi, the Patriots’ footballs starting at 12.5 would have been under-inflated by 1 psi and the Colts’ footballs starting at 13.5 psi would have met the NFL standards. But since we don’t know what the original Colts’ inflation pressure was and the NFL either doesn’t know or isn’t saying, we can only guess. I am only trying to define the range of possibilities.
