From what I've seen in two minutes of intense web research, an inflated football weighs roughly 14 to 15 ounces. Here's a more detailed analysis, which estimates the weight of air in a football at a pressure of roughly 13 PSI at 9.67 g. That means that if the footballs are underinflated by 10% above atmospheric (5% absolute), the football weight would be lower by roughly 0.5 grams.
So, if the football weighs something over 400 grams, what is the expected deviation of the football's weight by manufacture, and by environmental change?

That's not to say that it does seem odd that ALL of the deviations were on the low side. However, the Colts are sore losers, and the Pats won the SB without deflated balls, if just barely.

Stinkin’ Patriots. Dirtiuh den da Ray-dahs evah wuz.
NFL has become professional wrestling in shoulder pads. Except pro wrestlers take fewer steroids and don’t get arrested as often.
Amnesty for illegals, ISIS on the march, Obama taking over the Internet, the country coming apart at the seams, and there are still those out there worried about this so-called “deflate gate” BS?
Seriously?
This has been my assertion from the beginning...the NFL officials responsible for validating the footballs before the game neglected to do so, or at the very least, did not document the results of any such efforts. Thereby negating anything anyone may have believed or alleged about the inflation status of any football used in that AFC Championship game. The fault lies with the NFL officials for not doing their job.

What do you mean, an AFC or an NFC football?
What? I don’t know that.
Sorry, I was on a roll.
Am I the only red blooded American dude whose had it up to here with the NFL scandals and watergate moments and wants them to for the love of all that I good and decent just get back to playing football?
Maybe it’s just me.
Why would they be trying to catch the Pats in the act? Why not just properly inspect the balls and make sure they’re inflated properly? That would be the goal of a GM “expressing concern”, making sure the refs do their job. Which the latest leaks (no record of inflation at inspection time) say they didn’t.
There is something that has driven me crazy since the start of this controversy and it is the idea that weighing air versus air pressure is how you determine if a ball is under or over inflated. What is it with these commentators anyway? Am I all wet with regard to this matter? I never heard of, nor can I imagine that you can judge a ball’s inflation level by weighing it? It sounds preposterous to me.
A completely flat uninflated football weighs the same as a completely overinflated round football because air has no weight.
I thought this was all put to rest when it was discovered that an NFL employee was taking the original balls to sell and substituting them with others.........
