Test the Footballs

Inflate the football to normal pressure at room temperature. Check the pressure. Put it in the refrigerator and let it cool down to about 32F or so like at the game. Recheck the pressure. See how much pressure has been lost by cooling down the football. The Gas Laws say the lower the temperature the lower the pressure.

Or they could have collected the other 12 balls after the game and pressure tested them for comparison.

If you are suggesting that the pressure difference was due strictly to environmental factors, you are wrong.

Or quit cheating

Why didn't any of Indy's balls come back under pressure? Same conditions.
For what it's worth I don't really care and I think the entire story is being blown out of proportion and the next two weeks are going to suck.

Sounds like we have a topic for the next sports science.

how come no one else has this problem?
Bc they already know that

These 2 weeks are bad enough without all this stupid shite. Now they have more stupid shite to beat into the ground.

There didn't appear to be a problem with the Colts footballs.

I think temp in that in the formula works on the Kelvin scale. 40 degrees really isn't big enough to make that much of a difference.

its been about 8 years since chem classes, but using PV=nRT, solving for n at room temp using NFL pressure and volume standards, then solving for P(2) at freezing temp using the same V and n, the difference was just under 2 psi.

The first thing I thought was "What would the pressure drop be do to temperature"... Looks like there are multiple threads discussing it is quite possible for the pressure to drop 2lbs within 2-3hrs of being outdoors.
The subsequent question is, did they test the balls the colts were using to see if a similar drop occurred with their footballs?
I haven't seen anything confirming it
If there was a pressure drop with the colts, but not as significant, then did the Colts bring their balls back indoors after warmups or attempt to keep them warm on the sidelines, whereas the Patriots knowingly left theirs exposed to the elements in order to lose pressure?
I don't doubt the Patriots knowingly did everything they could to get the balls down to where they wanted, but did it go as far as deflating, or being mindful of ways to naturally lose pressure quicker.

I always thought the refs brought the game balls and kept them before the game in order to prevent stuff like this.

There are tons of cold weather games every year (much colder than this game) and this has never been an issue. Explain that.
