Welcome to the It’s a Numbers Game Football Blog Tour!
Celebrate the release of the newest addition to the It’s a Numbers Game series and, also, the start of football season.
This week 5 blogs will be featuring excerpts from It’s a Numbers Game! Football by Eric Zweig.
The book has a foreword by NFL superstar Patrick Mahomes, too.
Join us each day this week, so you can explore the stats, digits, and dimensions of the game.
And, of course, be sure to have a pencil and paper ready to try your hand at some fun gridiron calculations!
Having a Ball
Most leagues have very specific rules about the footballs they use.
A football must be made from four leather panels that are stitched together to form the surface.
Although you’ll sometimes hear people refer to a football as a “pigskin,” there’s no pig here.
The leather that is used is actually made from cowhide.
It must have small bumps on the surface, which make the ball a little easier to grip.
All leather footballs have laces.
In the old days, these laces were used to help hold the ball together.
These days, the laces are really just for show … though they can make the football a little bit easier to grip, too.
Inside the four leather panels is a rubber bladder which is inflated to give the ball its size and shape.
That shape is formally referred to as a “prolate spheroid,” but you’re more likely to refer to it as an oval, or as egg shaped.
Science Stuff
League rules in the NFL, the CFL, and the NCAA all say that the bladder inside each football is to be inflated to about 12.5 to 13.5 pounds per square inch.
If a ball is deflated a little bit it will be softer and easier to grip, which can make it slightly easier to throw for short passes.
An underinflated ball is also much easier to catch because it’s less likely to bounce off a receiver’s fingers.
Pounds per square inch—or psi for short—is a unit of pressure.
It’s the pressure resulting from a force of one pound applied to an area of one square inch.
Divide the pounds of perpendicular force by the square inches of area on which it is acting to get the pressure in pounds per square inch.
Did You Know?
Both teams in an NFL game must provide 12 primary and 12 backup balls to be used in a game no later than two hours and 30 minutes before the game starts.
Also, six more brand-new balls are shipped directly to the stadium by the company that makes them.
They are used in the kicking game.
