report.
The footballs are not supposed to be under 12.5 PSI. Look at the Pats balls. Five of them are in the 10s, according to one of the testers. Of 11 balls being tested by two testers, every one is under-inflated, and only one of the 22 tests had even one of the balls at 12 or higher. Thirteen of the 22 tests had the balls at least one full PSI less than regulation.
Same page, look at the Colts footballs. One tester had all four footballs at regulation, and the other tester said three of the four were under-inflated. So that's three of eight tests (not 3/4). The lowest football came in at 12.15.
So the Colts worst test on a football still had a higher PSI than the Pats highest-inflated football.
If the Pats were hovering around 12.5, this wouldn't be an issue.
But hey, why be a slave to facts and stuff.
