The NFL specifications say the footballs must be inflated to 12½ to 13½ pounds. Have you checked to see what the ball feels like if it is 10½ psi? Do you know how much temperature changes the psi?
How did the NFL decide that balls must be between 12½ to 13½ psi?
Maybe it does not matter a whole lot if the range were changed to 10½ to 13½ psi. Do you know?
Why take about other dimensions and sports when the subject is NFL specs for football inflation levels?
Hey, if you take fifteen percent of air out of a ball...in very wet conditions...and replicated that over a season of wetconditioned games, yes, receivers are going to catch more passes than higherinflated balls.
As for temperature, #1...it wasn't freezing on Pats sideline while being warm & balmy on Colts sideline...
#2...The weather was above freezing thruout the game...fifteen one degrees at gametime...and these footballs were exposed to direct air less than 2 hrs...
