I thought it was curious at best.I wonder if it was a coded message to the persons currently being interviewed to STFU. I'm convinced thats what they did now and its genius in a way. They can truthfully say they aired the balls up to the right pressure before inspection and did not tamper with them afterwards. However they knew the balls would universally deflate by a significant amount in time for Tommy Boy to have his Nerf ball to play with, clearly tampering with the rules.And again it wasn't the first allegation of it by an opponent so they probably had it pretty well perfected. Its the Patriot way and the asterisk will never go away.
I still think someone is going to get hit hard with penalties before its all said and done.

2. Both teams supply an equal number of balls they are checked by the refs and then given to the custody of the NFL ball boys/men and rotated in and out of the game.
3. The advantage of an underinflated ball is it's easier to grip. Troy Aikman for instance is on record of having significantly more trouble dealing with a wet ball in the elements. The implication being that if they were worried about Brady's ability to get velocity on the ball, the ability to catch the ball and to maintain control of it, then deflating the ball gives you an advantage they shouldn't have had.
It's a marginal advantage at best but I think the real issue is that organizationally they have shown themselves to be willing to break rules to get a competitive advantage and this isn't the first time they've been caught.

In that game it doesn't matter a single bit, the pat's would have won that game throwing pillows or rocks just as easily (besides, all the real scoring was done in the second have, with legit balls) so I won't comment on balls or air pressure any more.

There is not doubt about that but it stands to reason that this was not the first game this had happened. The Ravens game might have ended much differently had they been using regulation pressure (if they were using deflated balls).

But there's no proof of anything in that or any other game like there is in this one, which is why the demonstrated pattern is what needs to be addressed, not the single incident.

The balls are specifically made to hold their PSI in all weather conditions, and baring putting them in a freezer, the excuse of the drop in temp is "complete BS".
I've heard a lot of angry engineers calling into local and national sports radio to express their opinion that the common person has no basis to begin analyzing anything related to PSI. This is science.

This is science. I have no basis to say what could and could not happen, and I doubt that anybody here does either. I know that my car tires use to regularly lose 1-2 PSI overnight in cold weather of less than 40 degrees. If I am not mistaken, the footballs I use to throw in sub 30 degree weather would deflate somewhat as well. It's pointless for anyone without an extensive background in science to explain what is and is not reasonable. If the NFL has video of that equipment manager doctoring the balls, then there is some legitimate evidence. Reports are that they may in fact have that.
The rule of thumb is for every 10° Fahrenheit change in air temperature, tire pressures will change about 2% (up with higher temperatures and down with lower)
Distant Relative wrote:Answer me this. If you take a tire off of a vehicle that doesn't have 1 thousand pounds off weight on it will it loss as much pressure as the other 3 tires with the vehicle putting weight on them?
Strange comparison as a football isn't anywhere near a tire that has 1 thousand pound load on it.
Hawktawk wrote:The reason the car tire theory doesn't work is the volume of air is so much greater hence a greater potential to expand or deflate. This is more true the larger the tire.
35 psi works when it's empty, but with the added weight, I've had to air them up 50 psi in order for them to regain the same shape they had when the trailer is empty.

Expansion and contraction of the tire or football isn't the question. What we are trying to determine is how temperature affects air pressure. As gasses cool, they contract, and if they stay within the same confinement, the pressure will decrease.
Perhaps the relationship between temperature and air pressure isn't a straight line function, that the rate of pressure loss or increase changes as it gets colder or warmer. But until someone shows me that the 2% change in air pressure for every 10 degrees change in temperature isn't valid, I'll stand by my remarks.

Good advice for someone that doesn't have anything substantive to offer to the discussion.
