That professor overestimates the effects of temperature change by about double. To get to the levels the NFL measured the temperature of the football would have had to drop from around 80 degrees F to below zero.
With a professor like that for a mouthpiece, I would ask for a tuition refund if my kids were enrolled at Boston University.
To me the way rule 2 is written it leaves the door open to manipulation of game time pressure based upon temperature manipulation of some sort. I didn’t run any ideal gas law calcs to check the professors numbers. However I think it is a neat idea and not outside the rule as written to do this if you want a softer ball to play with. I admire innovation of this type.
