Tom Brady's venial sin

I am not inclined to fawn on any already puffed up, super -rich New England sports hero. But the public " crucifixion " of Patriot quarter back Tom Brady strikes me as silly and even outrageous. I have no expertise on pro-football. But why should there be ANY rule that frustrates the quarterback getting a firm grip on the football ? Why should the opposing team play with their own footballs ? What difference would it make if all the balls must conform to rigid air pressure standards anyway ? And given the facts of high school physics ( Boyle's Law ) should footballs be monitored with every incremental change in temperature ?
In WHAT games did Brady's stronger grip on the ball prove decisive for victory ? Using religious terminology he at most is guilty of a VENIAL SIN . Say three Hail Marys and sin no more , Tom .
