Rich Fisher (an avid Patriots fan, apparently) tweeted this
ESPN Sports Science piece which, among other things, claims that a football exposed to 10 degree F temperatures for an hour loses 20% of its psi, compared to room temperature. From 12.5 to 10.5 is a 16% drop, although it wasn't that cold that day.I don't think we have anything in the way of official reports yet, but it's been stated that the balls were initially approved I believe a couple of hours before the game (and probably done indoors). I guess that begs the question of why the Colts' balls checked out, but perhaps they were inflated to different initial levels, stored in different temperatures in the interim (indoor, outdoor?), or perhaps even simply, the Colts' balls weren't checked. I haven't read everything on the topic, but something from Peter King this morning that mentioned this seems to be assuming that the Colts' balls must have been.The alternative explanation of course would have to be far more nefarious.(I'd probably post less about this overall or in less ambiguous language if I were more mature. But I'm not.
