Deflate-gate: Patriots Coach Says 'Climatic Conditions' May Have Under-Inflated Balls Jan 24, 2015 By DEAN SCHABNER More From Dean »
New England Patriots coach Bill Belichick today said "climatic conditions" may have been to blame for the footballs that were under-inflated Sunday for the AFC Championship game, and said the team had not tried to tamper with them.
He said the team "followed the rules to the letter," denying any intentional wrongdoing by the Patriots.
"At no time was there any intent whatsoever to try to compromise the integrity of the game or to gain an advantage," Belichick said.

He’s getting close to blaming Climate Change, which would serve him well in both Boston and Seattle.
Finally, an explanation most Americans will buy.
but only NE balls... not Indianapolis balls... better to say nothing at all...
If the balls were inflated in a 70 degree locker room, then brought into 40 degree weather, the pressure will fall. Same amount of air, just lower pressure.
∂verybody is going to be looking for Bellichick and Brady to be drawn and quartered. If New England wins, there may be riots and upturned cars.
Where were the Indy balls inflated?
It was 45 F at half time when they were checked.
They would need to have filled and checked their balls at 50 F hotter. So a 95 F room.
“Finally, an explanation most Americans will buy.”
And they should buy it, absent any evidence to the contrary. Temperature does effect the gas in a tire. Some will say it would have effected all of the footballs but that’s not necessary true.
Those Ohio winters have nothing to do with it.
“They would need to have filled and checked their balls at 50 F hotter. So a 95 F room.”
Remember that a digital readout is always + or - one digit, that’s just the way it is...
in addition, he said he knew nothing about any of it during his pathetic press conference last week... “ask the quarterback...” and now mere days later he is adamant that no one did anything wrong... how is he so sure now? the New England Patriots are amazing miracle workers—in the last five days, they have made me a Richard Sherman fan...
Also, it depends on the mixture of gases in the ball. Add a smigion of low vapor pressure gas (H2O for example) and you could get the pressure drop at 45 degrees.
When a gas is pressurized, its temperature rises. If these balls were filled quickly, the inside temperature would have been higher than the room temperature — possibly above 95*F. After a few minutes, the inside of the ball would have reached room temperature, and thus have a lower pressure. However, unless the league rules mention all those variables; the balls might actually have been in compliance, when they were filled.
It shouldn’t be difficult to conduct an experiment, supervised by league officials. Fill a ball indoors — to the minimum allowable pressure. Take outdoors and wait for a half hour or so, and check the pressure.
Yes, but they were filled with helium.
ABSOLUTE UNITS:
plus 460 to go from F to Rankine (R)
plus 14.7 to go from PSIG to PSIA
Conditions:
Field temperature at half time: 45 F
Regulation ball pressure: 13.0 psig. (actually 12.5 to 13.5 pig)
Depressed ball pressure: 10.5 psig. (assumed. Going for a 2.5 psi deflation)
Room temperature required: xx F
Revised conditions:
T2a = 45 + 460
T1a = T1 + 460
P1 = 13.0 psig + 14.7 = 27.7 psia
P2 = 10.5 psig + 14.7 = 25.2 psia
Ideal gas equation is : PV=nRT
Rearrange to: (PV/nRT)1=(PV/nRT)2
Equation:
T2 = (T1 + 460 ) * (P1/P2) - 460
P1/P2 = 24.7/24.7 = 1.10 (So 10% hotter is required)
T2a = 505 R * 1.1 = 555 R
T2 = T2a - 460 = 555 - 460 = 95 F
So the a temperature change scheme requires a room 50 F hotter than field temperature.
It also requires that the balls be checked in the hotter room.
To avoid the same advantage for the other team, you need to have their ball room at field temperature.
An excellent suggestion.
For your scheme, you just need an air compressor delivering 95 F air !
It requires that you get the officials check the ball air pressure before they have time to cool off.
What is the rate of cooling of an NFL football?
I had heard it was a 2lb drop below legal. That’s a pretty large drop for a football.
Odds are it’s not some deep conspiracy but just a callous “cheat” of the rules that they got too slack on and went too far.
The most damning thing was when a guy claimed on the radio that their stats are atypical for cold weather performance.
Let’s see if the NFL treats this more serious than a coach telling his players to play hard.
where were the NE balls inflated? are they saying where they inflated these hot balls? what the temp was in the room where they inflated these balls? or is this just speculation... a possibility?
