I’m not slow witted.
I don’t come to quick judgments either.
When were the balls weighed again to discover the 20% difference?
At halftime.

There wasn’t a 20% difference! more like 7 and 8.9% could just be going from warm to cold environments. Ideal gas law - a 12.5 psi ball COULD deflate to 11.4 going from 72 F to 48F, the conditions of the day,
The lawyers almost get that right and many of the balls fell in that range, however some are too low for that.
