What I don't understand is how and where any kind of intentional deflation could have happened. IF I have understood this correctly, the current protocol is that the refs test the air pressure of the footballs inside their (warm) locker room 2 hours and 15 minutes before game time. The refs are in charge of the balls after that, until they take them out onto the field where they are then supervised by the respective teams. If those footballs are sitting out in the open on the field (which it seems they are), HOW did someone deflate 11 of them without being seen/noticed? Also, they were all 2 psi under. How do you surreptitiously deflate 11 balls to the same level without some sort of instrument or gauge- which would make it even more difficult to do without being seen? It's easier for me to believe that "something happened" to the gauge in the locker room while the refs were measuring the pressure initially, so either the first 11 or last 11 balls were faultily measured before they every went out on the field. That makes more sense to me than anything else. Interestingly/curiously, although it's purported that the under inflated balls would make it easier for the Pats to hold onto the ball, they scored the majority of their points in the second half, AFTER the balls had been re-inflated. If under inflation is such a benefit, you'd think they'd have scored more in the first half!
It's all quite mysterious, and it'll be interesting to see what the NFL has to say at the conclusion of their investigation.
