So I've played around with the physics a little bit. Turns out, I think NDT and Bill Nye are correct in their calculations.
 
Here is where I think some posters in this thread have messed up:
 
Say the ref's room is 75 degrees or 297K. And the halftime temp is 45 degrees or 280K. That gives us a ratio of 280/297 or .94. So the absolute temperature dropped by about 6%. This much everyone agrees with.
 
The balls have a gauge pressure of 12.5 PSI, and atmospheric pressure is (on average) 14.7 PSI. That gives the balls an absolute PSI of about 27.2. Take out the 6% due to the temperature drop, and we have a new absolute ball pressure of 25.6, or a difference of 1.6 PSI. This is the figure that people on SOSH have been quoting as correct. But it's not, because we still have to convert the ball's absolute pressure back to gauge pressure.
 
We can't simply subtract 14.7, because the atmospheric pressure has ALSO dropped due to the temperature change. The new atmospheric pressure will be 13.8. Subtract that from 25.6 and you get the ball's new guage pressure of 11.8. So we can only explain a change of .7 PSI due to temperature alone, which is exactly the numbers Bill and NDT quoted.
 
Except that the atmospheric temperature in the gauge room would still be 75 degrees. 
 
The pigskin would still be cold (thermal mass) and is also an insulator of unknown quality.

Is that about right?  Just want to confirm how absolutely cuckoo bananas this is.
 

I think this is a function of not interviewing Brady/BB until the Super Bowl is done.

When does the discussion turn to "What will the punishment for the Colts be?"  Assuming the Pats are fully exonerated, which I expect at this point, and assuming the leaks and tips came from the Colts (less sure, but probable), I would expect a fine against the Colts.  The NFL can't let teams throw around wild, unsubstantiated accusations with impunity.

He was all about the why did the Colts balls not change, refs always measure the balls properly pregame, and what did this guy do in the bathroom, and then Florio left and he said BB, Brady, and Kraft were all telling the truth and he's never known them to be liars. He also ripped on the NFL if this was a sting operation and said it would be a tremendous black eye for the league. He was all over the place.
 
Florio was every bit of Florio that you would come to expect. Said they had "circumstantial proof" in this case and the league only need a preponderance of the evidence. Blah blah blah.
 
I still wonder why the bigger question is why the Colts balls, if measured, didn't abide by the laws of science, but Bill Nye said Pats lied and that's not how science works, so...
 
I think it's probably because they never actually measured the Colts footballs at halftime.
Why don't these geniuses just repeat what BB and the staff did last week with a few dozen footballs as an experiment? Why is that such a difficult thing for people to understand?

Bedard did say at the end that this is not some little thing and thinks it is serious.  Said that the league isn't taking something little and trying to make a big deal of it.  Told everybody to just wait and hear what comes out (although he wasn't acting like he knew more than anyone else.
Best part is, in this situation, with what's been revealed so far, the Pats don't NEED the benefit of the doubt. Everything so far supports their position. If you're going to claim that you don't believe Brady and Belichick, don't preface it by saying it's because you're not going to give them the benefit of the doubt, preface it by saying it's because you're going to disregard logic, common sense, and basically everything else that undermines the position that you're determined to take.

Also their footballs didn't deflate at all in colder weather, which is direct evidence of tampering.

OK, I don't know if anyone has posted the full calculation NDG should have made, so here goes.
 
We are using the Ideal Gas Law. 
 
PV = nRT
 
Assumptions:
1. n is constant under these conditions. There are the same number of gas molecules just increasing the temperature to increase the pressure.
2. V is constant under these conditions. I know there is a very slight increase in volume when going from 11.5 psi to 12.5 psi, but I am assuming the same volume for simplicity sake.
 
So
 
P(1)V = nRT(1)
P(1)/T(1) = nR/V (constant)
 
P(2)V = nRT(2)
P(2)/T(2) = nR/V (same constant)
 
P(1)/T(1) = P(2)/T(2)
 
Using Guage Pressures and 2psi difference for footballs measured at STP (1 atmosphere, 68F)
P(1) = 10.5 psi
P(2) = 12.5 psi
T2(2) = 68F, 20C, 293K (room temperature)
 
10.5/T(1) = 12.5/293
T(1) = 12.5 x 293 / 10.5
T(1) = 348.8 K, 75.8 C, 168.4 F = WAY TOO HOT
 
Using Absolute Pressures and 2psi difference for footballs measured at STP (1 atmosphere, 68F)
P(1) = 10.5 + 14.7 = 25.2 psi
P(2) = 12.5 + 14.7 = 27.2 psi
T2(2) = 68F, 20C, 293K (room temperature)
 
25.2/T(1) = 27.2/293
T(1) = 27.2 x 293 / 25.2
T(1) = 316 K, 43 C, 109 F = STILL HOT, but below NDG value
 
So, I do not know where NDG gets 125 F from a 2psi (~15% change). Unless I made an error, NDG just screwed up the calculation without necessarily using the guage pressure.

Calling 2psi a 15% change is itself making a gauge pressure error. 2 is 16% of 12.5, but that's a junk calculation.

2 PSI is about 7.4% of the actual pressure in a 12.5 PSIg ball: 12.5 PSIg + ~14.7 PSI atmospheric ~= 27.2 PSIa. 2/27.2 ~= 0.0735.

No, I think he means there are whispers that the Pats deflated their own footballs in all three of the Ravens, Packers, and Colts games.

Borges asked Brady in the most condescending way possible how he couldn't notice a 15% difference in air pressure when the DB of the Colts noticed it (and baseball players notice differences in their bats, blah blah).  So it was actually a maximum 7% difference noticed by the equipment guy.  Not that I needed more proof Borges is a disingenuous idiot.

Now let's do the calculations using a 1 psi pressure drop
 
We are using the Ideal Gas Law. 
 
PV = nRT
 
Assumptions:
1. n is constant under these conditions. There are the same number of gas molecules just increasing the temperature to increase the pressure.
2. V is constant under these conditions. I know there is a very slight increase in volume when going from 11.5 psi to 12.5 psi, but I am assuming the same volume for simplicity sake.
 
So
 
P(1)V = nRT(1)
P(1)/T(1) = nR/V (constant)
 
P(2)V = nRT(2)
P(2)/T(2) = nR/V (same constant)
 
P(1)/T(1) = P(2)/T(2)
 
Using Guage Pressures and 1psi difference for footballs measured at STP (1 atmosphere, 68F)
P(1) = 11.5 psi
P(2) = 12.5 psi
T2(2) = 68F, 20C, 293K (room temperature)
 
11.5/T(1) = 12.5/293
T(1) = 12.5 x 293 / 11.5
T(1) = 318.5 K, 45.4 C, 113.7 F - HOT, but still below NDG
 
Using Absolute Pressures and 1psi difference for footballs measured at STP (1 atmosphere, 68F)
P(1) = 11.5 + 14.7 = 26.2 psi
P(2) = 12.5 + 14.7 = 27.2 psi
T2(2) = 68F, 20C, 293K (room temperature)
 
26.2/T(1) = 27.2/293
T(1) = 27.2 x 293 / 26.2
T(1) = 304 K, 31 C, 88 F - PERFECTLY RWASONABLE TEMP INCREASE FROM RUBBING

I agree. I was only using NDG's Tweet for that value. I know it was faulty like the rest of his calculation.

I don't know why you are doing this to yourselves after 9 days of this nonsense.

If I'm Kraft, I move the broadcast rights after expiration of the current agreement. When F & M then get all butt hurt and provide low comedy by wrapping themselves in the 1st Amendment, I'd then laugh. Then I would make the common sense point that I have no interest in ties with cynical, dishonest people who tarnish my brand.

98.5 is part of CBS radio. Given Kraft's relationship with CBS there is no way they're moving the broadcast rights.

Oh, I know what he's getting at, I just think it would be hilarious if one of the "problem games" was with an opponent who admitted to trying to game the very same rule.
 
BTW, Around the Horn is on (silent but close-captioned, thank God, or I might have had an aneurysm) on a TV where I'm sitting right now and J.A. Adande just said the "analysis" about the Patriots never fumbling might actually be the strongest evidence against them.  I'm pretty sure he meant it as a compliment.

I'd love it to mean more, but it just may be his a) looking at the INT ball when the Colts complained and/or b) squeezing the Colts balls for quick comparison.
