FOXBORO -- Patriots coach Bill Belichick, at an impromptu Saturday press conference, reiterated that he is confident his team "followed every rule to the letter" in terms of how it handled its footballs before and during last week's AFC Championship Game.
As the Patriots continue to be enveloped in an NFL investigation as to how they utilized under-inflated footballs against the Colts, Belichick offered an impassioned defense of his team and staff, saying, "We try to do everything right. We err on the side of caution . . . As far as I know, we did everything as right as we could do it."
Belichick also provided a more scientific explanation of how Patriots footballs became under-inflated on Sunday. According to him, the team simulated a game-day situation earlier this week focused on the preparation of footballs. He said the team's process to create "feel" on the football increases the pounds-per-square inch by approximately one pound.
He said the Patriots found that once footballs were on field "for an extended period of time" it dropped the PSI by 1.5 pounds, and that bringing the footballs back inside to measure PSI raised the pressure by about .5 PSI.
