No one knows how great an impact deflated balls had on any of the Patriots wins. I believe it was minimal at best.
The Pats scored 28 points after the second half of the AFC Championship Game with inflated balls compared to 17 with deflated balls. Seems to me like they got better playing with a fully inflated ball. And Brady seem to be throwing just fine in the Super Bowl with a fully inflated ball. And the Pats had no fumbles with an inflated football.
As for Spygate, teams have been trying to intercept other team's signals since the beginning of football. Jimmy Johnson even acknowledge he did the same thing. I guess that means our Super Bowl wins were tainted.
Besides, even if the Pats were busted for recording other team's practices, you still have to stop them. It's like Jimmy Johnson used to say about our offense. It was basic. You knew what was coming. Now stop it. Yet teams couldn't.
I'm not excusing "cheating." If the Patriots cheated, they should be punished. But this is the NFL with the best of the best playing the game. Even if you did gain a slight advantage, you win, what? One maybe two games? The Patriots have been dominant for 15 years with nine AFC Championship appearances, six Super Bowls and four wins.
Cheating doesn't give you
THAT much of an advantage.
The common denominator in all great dynasties (teams that make multiple Super Bowl runs) is a great coach, a great quarterback and a good/great defense. (Green Bay - Bart Starr, Vince Lombardi) (Pittsburgh - Chuck Noll, Terry Bradshaw, Steel Curtain) (San Francisco - Bill Walsh, Joe Montana) (Denver - Mike Shanahan/Dan Reeves, John Elway) (Dallas - Jimmy Johnson, Troy Aikman) (Dallas - Tom Landry, Roger Staubach) and (New England - Bill Belichick, Tom Brady).
You must have the coach, the quarterback and a defense that's either great or good enough.
The Patriots have had all three, but primarily the coach and the quarterback.
