According to one source I found, an un-inflated football weighs 411 grams and an inflated football weighs 421 grams. The difference of 10 grams is about .35 ounces. If the theoretical football was under-filled by 25%, that would be a weight difference of 2.5 grams or about 0.088184904873951 ounces. That would be difficult to measure on a scale in a lab under excellent conditions. On the sidelines, during a cold and wet game - yeah right. Now if the footballs were filled in a warm locker room and brought out into the cold, they might "deflate" slightly but come on. I call sour grapes on this one.

underinflated. The balls are required to be inflated between 12.5 and 13.5 pounds per square inch and weigh between 14 and 15 ounces. Once approved by the referee, the balls are then put into ball bags and are set on the sidelines for each team. The ball bags are not guarded or watched in any way. When an official calls for a new football, a team's designated ball boy will get a new football from the ball bag and give it to the official.

Seems like the easy answer is just to have the League provide all the balls. The NFL makes billions upon billions of dollars and they insist to make the teams ante up for 12 footballs per game? Then again, the NFL hasn't really been very good in the balls department as of late.

Apparently, according to the news reports, the league does provide the balls, but they are put in the charge of the teams so down balls can be roughed up a bit, but are not checked from the time each team takes possession of "their" share of the balls to gametime. Perhaps they should be like baseball and given to the game officials to monitor.
 
The balls are checked two hours and fifteen minutes before game time. After they are check they are under control of a uniformed NFL official until approximately ten minutes before kickoff. That is from USA Today.
 
Evidently, Brady has come out stating that he had no knowledge. Hmmm... let's see. The Colts receiver that intercepted a pass noticed but the passer didn't.
