Check the pressure in balls used by the Patriots

[gjv001]

We all know that an underinflated football is better the throw, catch, and hang on to in cold weather. The Pats have a history with ball inflation, let us not be a victim.

Wouldn't the cold temperatures actually have a deflating effect on the ball already?

Goodell just approved the use of wineskins as a football substitute

PSI wise, yes.  According to some of the players a colder football makes it harder.  Like catching a brick.

The ideal gas law states that PV = nRT. So as T goes down, P x V must go down as well. However if additional air is pumped into the ball (more n), then the effect of lower T is negated.  So if they pump the balls up to a certain pressure while at at game temps, all is well.

Our DBs will be checking them all game as they bat them down.

Enough of the P x V talk, this is a family-friendly message board 😉

I can't handle all this pressure

They do and it's a significant one.

why are you telling us to check the pressure?

While teams still provide the balls, the NFL takes the pressures and has the balls under their control the entire game.  The balls are also randomly checked for funny business.  It's much harder the Cheats to Cheat, but we should be forever vigilant against those Cheatin' Bastards.

Seems to be a lot of laws about balls.  Not sure if that's a good band name, book title or some social issue....

Sad part is, we complained about the Cheating patriots deflating the balls for years & the NFL didn’t do anything about it until the other, non-AFC East, teams started complaining about it. 
Let’s Go Buffalo!!!!!

If it’s true, and footballs feel like bricks Josh should just unload everything he has into a fastball right at JC Jackson on the first play of the game.  Set up a bubble screen for Diggs, while Jackson is trying to maneuver himself, have josh unleash a ball into into Jackson’s newly broken hands. If they don’t break, no worries…..he’ll still drop the sure pick.

When we bring the basketballs out of the trunk for practice they are all very soft. 20 minutes later they are fine.

Right...T goes up with constant n, hence P x V goes up as well.

Temperature and pressure vary directly.
