Plot and statistics of mean and standard deviation from measured Colts footballs at 2015 AFC championship game. The Wells Report considers the lower of the two plotted lines to be accurate. Y axis 10 to 13 psi Colts ball Make sure the ball is completely deflated before attempting to remove the needle or valve tool to avoid injury. Travis Durkee (January 21, 2015). "Ex-NFL referee: All 12 Patriot footballs were underinflated". Sporting News. Archived from the original on January 25, 2015 . Retrieved January 24, 2015. News reports say that 11 of the 12 game balls used by the New England Patriots in their AFC championship game against the Indianapolis Colts were deflated, showing about 2 pounds per square inch (psi) less pressure than the 13 psi required by the rules, so it seems that the most bizarre sports scandal of recent memory is real. But there are still plenty of questions: why would a team deflate footballs? Could there be another explanation? And most importantly, what does physics tell us about all this?

The messages also describe requests from McNally for shoes and signed footballs from Brady - a four-time Super Bowl champion and future Hall of Famer - in exchange for deflating balls. What did the 'deflator' do? The needle of your football pump should be inserted into the ball’s inflation hole very carefully. Try to avoid inserting it at an angle, as this could result in damage to the bladder inside. If there’s resistance, try lubricated the inflation needle with some cooking oil.

Exponent believes the measurements for Colts ball #3 involve some sort of transcription error by the original NFL transcriber, as it is the only row that reverses the usual logo vs. non-logo gauge differential. So far we have presented a scenario in which, if the NFL were terribly misguided and took all measurements of footballs immediately, they could have ended up with a football that was measured pre-game at 12.5 psi at 92 degrees and later measured at halftime at 10.4 psi at 48 degrees. That is a difference of 2.1 psi, which is about equal to the reported missing 2 psi. a b c Orr, Connor (April 25, 2016). "Tom Brady's four-game suspension reinstated by court". NFL.com.

Did you ever have to make do with a partially deflated football when you were a child? If you’re of a certain age, you’ll remember such an occurrence. If only someone had a pump, eh? Because even a partially underinflated football can significantly change the way it plays. Thankfully, football pumps are cheap and ubiquitous these days. But this counts for nothing if you don’t know how to inflate a football properly. What Are FIFA’s Regulations on Soccer Ball Pressure? HeadSmart Labs found that similar weather changes caused an average 1.8 psi drop in football pressure. [31] They also reported that the air in an electric pump could reach 130°F.Leonard, John (November 25, 2015). "Deflategate transient analysis". YouTube. John Leonard . Retrieved December 14, 2015. Under the Ideal Gas Law, the working theory is that the air pressure in the balls would rise during warm days and fall during cold days, which is what happened. Playmakers reveals that "numerous" measurements made at halftime of games during the 2015 season produced numbers beyond the permitted 12.5 to 13.5 PSI levels and correlated to the Ideal Gas Law. That means the footballs used by the Patriots were consistent with the conditions that they were playing in that day as it relates to the recorded data in 2015, distorting those initial allegations of wrongdoing. Kraft stated at a news conference that "I was wrong to put my faith in the league" and apologized to the team's fans for accepting the "harshest penalty in history of NFL for an alleged ball violation" because he thought that cooperating would help exonerate Brady.
