BREAKING NEWS:

Schefter's sources are saying the NFL is having trouble finding evidence that the Pats altered the ball, and it may have only been a 1 PSI difference!!!!

STOP THE PRESSES!!!

hey, rocket man......that's exactly what I am saying. They are "cheating" within my acceptable margins

Yeah... I'm with AJ on this one.

A 3 man wolfpack has formed!!!

Think of the example they're setting for your children!

To what, be punished for breaking the rules?

I'm sure you'd agree there are varying types of rule breaking with varying types of consequences, no? I tend to not worry about the ones that are small infractions that warrant small punishments. I don't see what's so wrong about that, though I know you joking there...kinda lol.

im breaking rules as i type this.. heh..

Team AJ on this one. It should be a non story and it's Thursday and we still hear about it.

Was just wondering if they'd do one this year. Nice!

So this is why I rarely watch SportsCenter.

This is hilarious, going all out on DeflateGate.

They're asking Mark Brunell whether he believed Brady and Belichick today, because when I decided to put ESPN on, I was wondering, "Man, I wonder if Mark Brunell believes Tom Brady."

They did a "test" today with brunnel wingo and bettis, and asked if they could tell the difference between 3 balls (over, under, and even).


Ummmm yea! If you're fucking looking for it! They're pro god damn athletes lol

This is silly

Dear god, some scientist from U of I is on now trying to say that the outside temps dropped the ball pressure and blah blah

well that is probably the reason for it.

If they filled them to the minimum required pressure in a room that was 90 degrees F, then yes.

Are you asking for the math?

Absolute pressure in properly filled (nominal) football = 13 psi measured + 14.7 psi atmospheric = 27.7 psi
Absolute pressure in properly filled (minimum) football = 12.5 psi + 14.7 psi = 27.2 psi

Reported temp at the time of kick-off = 283.15 K (50 degrees F)

Reported measured pressure in footballs when checked = 10.5 psi (so + 14.7 psi yields 25.2 psi absolute).

25.2 psi/283.15 K = 27.2 psi/ X K

Solving for X yields 305.6 K (or 90.41 degrees F).

are you taking into account that the balls were more than likely pumped in a locker room, and brought outside to a colder temp?

Ummmm...

I assumed the balls were filled/checked indoors and then later checked outdoors (which is where the discrepancy would have been discovered, presumably). That was the entire point of the calculation determining the change in pressure due to the change in temperature.

Guess I lost you somewhere.

Dak that was some confusing Math you did. Well done.

There's a reason Dak has the job he has, and we don't

He probably rattled all that off without even thinking about it, too

well some scientist from Boston had this to say

“One complication with the pressure units that we usually use, in this case PSI (Pressure per Square Inch) is that we are measuring the pressure above the atmospheric pressure,” Schmaltz said. “Air at a fixed volume- and I assume the size of a football stays pretty much the same whether it has a PSI of 13 or 11- if the size stays the same, and you change the temperature of the air, the pressure inside the football changes as well.”

The key question, as outlined by Schmaltz, is where the balls were tested prior to the game.If the balls were tested indoors, where the temperature was likely above the 50 degree temperature outdoors Sunday, then the pressure inside the ball would drop once the ball is moved outdoors and begins to cool off.

“If they had inflated the balls inside the building and put it to the minimum amount, and then brought it outside to temperatures that were about 30 degrees lower, that would drop the PSI by between 1 and 2,” Schmaltz explained.

According to Schmaltz, once the temperature of the air inside the ball drops to the temperature of the air outside the ball, the PSI would be changed. Schmaltz estimated that it would take no more than 30 minutes for the temperature of the air inside the ball to acclimate to the temperature of the air outside.

“After the game, if you take the ball inside to a commissioner’s office or another warm place, the air in the ball would warm up again and the PSI would go back up,” said Schmaltz.

so basically what i said til Dak came in with some math
