Sorry, but the only ball that measured below 11.5 PSI was the one the Colts tested. So if the Colts balls went from 13.5 to 12.5 and the Pats balls went from 12.5 to 11.5 would that satisfy you? And they certainly allow the teams to select if they want the ball at 12.5 or 13.5 when they approve them.

Please provide the source that the Colts balls were 12.5 before the game and at half. That seems more suspect than anything as everyone agrees there should be some decrease in pressure from weather. There is a range of PSI that the balls can be approved before the game so just because they were approved does not…

What PSI where the colts balls when they were tested prior to kickoff? Could they have been 13.5?

No if you removed All the pressure from a football that would mean you would have a vacuum (trust me there is not a vacuum in an empty football). But if you remove all the AIR from a football you are equalizing the pressure inside and outside the football, so the pressure inside the ball would equal the air pressure…
