The NFL found out about the footballs being deflated by one of the Colts defensive players noticing that the football thrown by the Patriot's quarterback seem a little lighter than usual. At half time the referee measured the pressure of the footballs and found that 12 that didn't meet the requirements of the rules. The ball pressure matters because if it's under weight, it can be lighter to catch or easier to throw. GO SEAHAWKS!😄💙💚🏈
