Letter: Temperature doesn’t affect footballs enough to matter

To the editor:

Temperature effect on football pressure is a red herring, perhaps suggested by an under-informed lawyer.

The variation is 2 percent per 10 degrees Fahrenheit. To produce a 2-psi difference for a 12.5-psi standard pressure the temperature would have to drop 80 degrees below the temperature at the time of inflation.

Legal conjecture cannot override basic physics.
