Um, I'm very familiar with the evidence, and I re-read large swaths of the Wikipedia article to make sure I was not misremembering, so I gotta ask, what evidence do you think there was?

In terms of evidence that they did not deflate the balls let's start with the Ideal Gas Law. Next, during the game in question the NFL started testing the Colts balls as well and found 3 of 4 were also low, then they stopped testing them, how odd. Then it came out that the NFL intentionally deleted evidence from the rest of the 2015 season of pressure measurements which would have aligned with the so called "deflated" balls. Next, statistical analysis of Tom Brady's passing metrics indicate he plays better with higher inflated balls, not lower. Notable is that he had better numbers in the second half of the Colts game, after the refs "properly inflated the balls" than in the first half. Next, the NFL to this day has refused to admit they had an issue with lack of consistent PSI inflation of footballs, yet they redid their entire process after that season and there hasn't been an issue with under or overinflated balls again. Last, this lovely quote from the Wikipedia article you told me to read, when asked by a judge what evidence there was against Brady the NFL lawyer said there was: "no direct evidence Mr. Brady clearly knew about this."
