Hard to believe a multi-million/billion dollar industry failed to know to check the balls for air not helium and at ambient temperature at the game location (altitude/parametric pressure). With all the controls over the kicking balls to prevent the kickers from microwaving the ball to increase the air temp inside the ball and other modifications; it is a far stretch of credibility to think that these professionals just had an "oops" moment and unintentionally allow the air density to contract below the allowable pressure. Even kids in a pick-up game at the park know to check the ball's inflation in the New England area in the dead of winter.

Very well stated "plausible denial" though, Dr. Arnold; maybe you missed your calling and should have been an attorney. However, hats off; you are a true Patriot . . . fan! LOL - Ed Pipalski
