2. There's a difference that all these ex-quarterbacks are not taking into account when they say, "Every team doctors the footballs." Former quarterback Matt Leinart tweeted something Wednesday that many quarterbacks were saying in different ways: "Every team tampers with the football. Ask any QB in the league, this is ridiculous!!"
Every quarterback can tamper with the 12 footballs assigned to his team in the days before the game. In the NFL, each team is allowed weekly to break in 12 new footballs as it sees fit, according to the quarterback's preference. That includes taking the shine and slipperiness off the new balls, and compressing them and working them in to soften the leather. By rule, those 12 footballs are then delivered to the officiating crew on site 2 hours and 15 minutes before the game begins.
At that point the head linesman inspects each football with one or more members of his crew. If need be, the officials will clean off the balls. Then they will insert a needle into the balls, one by one, to ensure the balls are inflated to the proper pressure: between 12.5 and 13.5 psi. If a ball is underinflated, an electric pump is used to fill it to the requisite level. Then all 12 balls are marked by silver Sharpie with a referee's personal preference of a mark-Gene Steratore's crew uses the letter "L," for Steratore's fianc?e, Lisa-and put back into the bag, and zipped. The bags are handed to the ballboys minutes before the opening kickoff. If it's raining, or bad weather is on the way, the officials might tell the ballboys to change the ball on every play, whether it hits the ground on the previous play or not.
To sum up: Yes, the quarterback or his equipment staff can break in the balls in whatever way they want a couple of days before the game. But no, the quarterback cannot dictate the level of air pressure in the ball. Or at least he cannot do it legally. And the low air pressure in the Patriots' footballs is why this is a story.
