A couple of possible reasons:
1. The Colts are butthurt whiny bitches who didn't like getting their asses handed to them. Just because no one has complained about weather deflating balls before doesn't mean that weather has never deflated a ball.
While perhaps this is the case, it definitely was not the first time a team has lost badly in cold weather. Hard to believe others have not been "butthurt" after an ass kicking in the cold.
2. Teams are allowed to reinflate the balls over the course of the game. Example: if a QB likes his ball at 13.0 PSI and it deflates to 12.2 as the game progresses, they can add air to bring it back to 13.0. If Brady likes a softer ball, they'd just let the decline in pressure happen naturally and not pump it back up. They're under no obligation to continually check the ball over the course of play.
Again, why has this never been an issue before? Hundreds of games have been played in similar conditions. Surely Brady isn't the first QB to prefer a slightly deflated ball.
3. Amontons' Law of Pressure-Temperature is REAL. Again, why oh why do people keep ignoring this scientifically factual component of this whole thing?
Not sure how you think I am ignoring this concept. In fact, I am addressing it directly. And giving you the benefit of the doubt. If footballs deflate at the rate that you insist, why is this the first time an opposing team has drawn attention to it?
I'm not saying "Brady did it but who cares because he doesn't need an advantage." I'm saying, Brady has whooped on people in much worse and DIDN'T cheat, so why would he risk it this time.
That's what we are all trying to figure out. But that is an incredibly weak defense. "Lance Armstrong won a ton of races already. Why would he start doping now? Why take the risk?"... Who the hell knows, but cheating is cheating is cheating.
