Last night, it was revealed that the NFL had determined that 11 of the 12 footballs the Patriots used during Sunday's AFC Championship were underinflated by a significant amount.
Teams provide 12 footballs bearing their logo that are tested two hours prior to kickoff. The first underinflated ball was noticed when Patriots QB Tom Brady threw a pass that was intercepted by a Colts defender, who then told an official that the ball felt underinflated.
