text: Anderson recalls that most of the Patriots footballs measured 12.5 psi, though there may have been one or two that measured 12.6 psi. No air was added to or released from these balls because they were within the permissible range. According to Anderson, two of the game balls provided by the Patriots measured below the 12.5 psi threshold. Yette used the air pump provided by the Patriots to inflate those footballs, explaining that he purposefully overshot the range (because it is hard to be precise when adding air), and then gave the footballs back to Anderson, who used the air release valve on his gauge to reduce the pressure down to 12.5 psi.
