However cold weather can be beneficial for throwing and catching the football as cold weather can decrease the pressure inside the football if exposed to the weather for a long period of time. Regulation pressure of a football is approximately 13 PSI (89632 Pa), the average volume is 0.0046 cubic meters, and the average amount of moles in a football is 0.17 moles. The minimum pressure that the football could have attained during the Ice Bowl is calculated below.
PV = nRT
P(.0046) = (0.17)(8.314)(248)
P = 76200 Pa = 11 PSI
This pressure is approximately equal to the pressure in the footballs during deflategate, meaning that the footballs in the Ice Bowl could have deflated to a prohibited level because of the frigid temperatures. However this decrease in pressure occurs over a larger span of time and likely did not reach this pressure during the football game. Additionally any benefits that the flat football produces were likely balanced by the detriments of numb hands and icy fields.
