Somebody needs to test the pressure drop due to the temp change. Not sure if the balls are kept warm or not though.
Here is some faulty MIT math....guy isn't smart enough to consider the balls likely to be somewhat elastic and so the volume is not constant. Likely acts like a volumetric spring to maintain some of the pressure. Nice try though.....for a homer.
A Massachusetts Institute of Technology postdoctoral associate, who asked not to be identified, agreed with Naughton’s calculations and even sent the Herald a formula that predicted a change of 1.78 psi by halftime if the balls were filled at room temperature. The temperature on the Gillette Stadium field at kickoff was about 45 degrees.
