So after reading about spygate this is what i found.....
New England Patriots were disciplined by the league for videotaping New York Jets' defensive coaches' signals from an unauthorized location during a September 9, 2007 game. Videotaping opposing coaches is not illegal in the NFL, but there are designated areas allowed by the league to do such taping. Because the Patriots were instead videotaping the Jets' coaches from their own sideline during the game, NFL Commissioner Roger Goodell deemed it to be in violation of league rules.
NFL fined Patriots head coach Bill Belichick $500,000 (the maximum allowed by the league and the largest fine ever imposed on a coach in the league's 87-year history) for his role in the incident, fined the Patriots $250,000, and docked the team their original first-round selection in the 2008 NFL Draft which would have been the 31st pick of the draft.
On September 10, 2007, Belichick was accused by the Jets of authorizing his staff to film the Jets' defensive signals from an on-field location, a violation of league rules.
Coach Eric Mangini—a former Patriots assistant coach later stated "I didn't think it was any kind of significant advantage, but I wasn't going to give them the convenience of doing it in our stadium, and I wanted to shut it down. But there was no intent to get the league involved. There was no intent to have the landslide that it has become."
After footage from the actual tape was aired on Fox NFL Sunday on September 16, former Dallas Cowboys head coach Jimmy Johnson claimed, "This is exactly how I was told to do it 18 years ago by a Kansas City Chiefs scout. I tried it, but I didn't think it helped us." Johnson also said, "Bill Belichick was wrong because he videotaped signals after a memo was sent out to all of the teams saying not to do it. But what irritates me is hearing some reactions from players and coaches. These players don't know what their coaches are doing. And some of the coaches have selective amnesia because I know for a fact there were various teams doing this. That doesn't make [Belichick] right, but a lot of teams are doing this."
So A. This wasn't bradys doing and i dont think should make him a "cheater"
B. It was ok to film the other team just not from your own sideline apparently. Jimmy Johnson said he filmed the other team when he was coaching but didn't think it really helped him or his team. He also said that a lot of other teams were doing the same thing. Eric mangini, the jets coach who first accused the pats of cheating and brought this all to light, Said he didn't think it gave the pats any advantage. Steelers chairman Dan Rooney stated that "We consider the tapes of our coaching staff during our games against the New England Patriots to be a non-issue. In our opinion, they had no impact on the results of those games."
Deflategate: During the first half of the AFC Championship Game, Patriots quarterback Tom Brady threw an interception to Colts linebacker D'Qwell Jackson. After the play was over, Jackson handed the ball to the Colts equipment manager for safekeeping as a souvenir. Early reports suggested that Jackson was the first to suspect the ball was deflated, but Jackson said he did not notice anything wrong with the ball he caught. Jackson says he actually did not even know the ball was taken or that the controversy existed until he was being driven home from the team's charter plane after the Colts had arrived in Indianapolis. "I wouldn't know how that could even be an advantage or a disadvantage," Jackson said. "I definitely wouldn't be able to tell if one ball had less pressure than another." After Jackson's interception, a Colts equipment manager measured the pressure of the ball on the sideline, even though this is prohibited[citation needed](though the Colts were not penalized), and the team notified NFL Gameday Operations that the ball measured below the permissible range.
At halftime, NFL officials inspected the footballs. Former NFL referee Gerry Austin initially, and incorrectly, stated that 11 of the 12 balls used by the Patriots were measured to be two pounds per square inch below the minimum amount, but later reports refuted this allegation, citing only a single ball was two pounds per square inch below the minimum, while others were just a few ticks under the minimum.
According to NFL official Dean Blandino, referees do not log the pressure of the balls prior to the game, or check during the game, and did not do so in this case. Walt Anderson, the referee, gauged the footballs. The Patriots' game balls were re-inflated at halftime to meet specifications and were reintroduced into the game.
The pressures of four of the Colts' footballs were measured at halftime using two gauges, and were found to be within regulation on one of the two gauges, but not on the other gauge. The remainder were not measured because, according to the Wells Report, "the officials were running out of time before the start of the second half."
The Patriots led 17–7 at the half; in the second half, the Patriots scored 28 points for a final score of 45–7. It was the 50th win by the Patriots in the rivalry. Given the crushing victory by the Patriots, there is a consensus that the Colts would still have lost even if the footballs were properly inflated.
HeadSmart Labs found that similar weather changes caused an average 1.8 psi drop in football pressure. They also reported that the air in an electric pump could reach 130 °F.
Dean Blandino, NFL head of officiating, confirmed on January 29 that the NFL checks, but does not log, the pre-game pressure of each football, and that there is therefore no record of where in the 12.5 to 13.5 pound range each Patriots and Colts football was before the game.
Dean tested a couple in the office and had one underinflated and one to specs, and you really couldn't tell the difference unless you actually sat there and tried to squeeze the thing or did some extraordinary thing. If someone just tossed you the ball, especially in 20 degree weather, you're going to pretty much play with the ball. They are going to be hard. You're not going to notice the difference.
So apparently the colts had their own footballs measure with too low psi on one of the gauges used. Were they cheating too? Or was the weather causing the balls to drop in psi?
The NFL head of officiating said that you cant really tell the difference in a slightly under-inflated football (that is what i thought as well) especially in 20 degree weather.
I found some interesting stuff that I didn't know about when researching these things.
After researching that stuff i found that brady is still the GOAT among QB's
