So if the temperature inside the stadium rooms was 70 degrees and the outside temperature was 45 degrees, that's only a difference of 25 degrees, 15 degrees short of the required 40 degree difference. We need the footballs to have started at a temperature of around 85 or 90, not 70.
Consider that its not the temperature of the ROOM where the balls were filled, but the temperature of the AIR that went INTO the balls that would need to be 85 or 90 deg. It is not unusual that an air compressor would heat the air as it compresses it.
I don't know, this is one of the strangest "scandals" I have ever heard of. What puzzles me is why does the NFL not supply balls or at least have an official who is responsible to inflate them?

Whoever calls me ignorant shares my own opinion. Sorrowfully and tacitly I recognize my ignorance, when I consider how much I lack of what my mind in its craving for knowledge is sighing for... I console myself with the consideration that this belongs to our common nature. - Francesco Petrarca
"Nothing is easier than to persuade people who want to be persuaded and already believe." - another Petrarca gem.
Ignorance is a most formidable opponent rivaled only by arrogance; but when the two join forces, one is all but invincible.
