Perhaps... Brady's mistake was going too far in slapping the rule book in the Ravens' face after Belichek made Harbaugh look bad. Game balls were submitted to his liking, on the soft side just like Rogers tries to do but on the hard side. Refs approved them by feel without using a gauge. During a closely contested first half , Harbaugh makes a call knowing what kind of balls the Pats like to use(to the NFL or Colts). NFL responds by making a proper check, finds the balls underinflated, re-inflates to proper pressure then the Pats come out and destroy the Colts. Don't hear much from the Colts because they get blown out using properly inflated balls.
Harbaugh is sitting back and really enjoying watching everyone on the Pats squirm. Pats get fined 25k for using underinflated
balls, no proof is found that anyone deflated the balls after their initial approval and the NFL looks bad for not properly checking their pressure. Relationships are cemented in contempt. Move on.
