Various explanations were debated at the time, including physics theories that explain how temperature and other conditions effect pressure. McNally later said he regularly took footballs into the bathroom before games, but the report did not find those claims plausible. Leonard, John (November 25, 2015). "Deflategate transient analysis".

February 18, 2015 . Retrieved February 23, 2015.For most footballs the deflation process is simple. Insert an inflation needle into the ball’s inflation hole. This will open the valve. And instead of pumping air inside, squeeze the ball hard to push the air out. Look After Your Footballs Let's now examine the range of ball pressures that are possible during an NFL game even when properly inflated at room temperature. We've seen that even a 48 degree F game can have a noticeable effect on ball pressure, so let's explore the full range of weather possibilities.

The rest of the football's mass comes from its materials, such as the leather and rubber, which add up to about 14 ounces, Eads said. On August 4, as part of the appeals process, the transcript from Brady's appeal hearing was made public. Analysts pointed out that the transcript raised numerous issues regarding both Goodell's ruling and the Wells Report. For example, Goodell's decision upholding the suspension stated: O'Connor, Ian (May 12, 2015). "Tom Brady should skip appeal, tell truth now". ESPN.com. ESPN Internet Ventures .

Colder gas molecules move more slowly [and], hence, don't hit the walls as hard, and so the pressure is less," Eads said. Rush Limbaugh (January 21, 2015).

It's also possible that the pressure of a football filled in a warm room will drop once it's taken into the cold outdoors. Even in the most extreme case imaginable, the pressure difference would reaslistically be no more than 1 psi rather than the 2.1 psi associated with instantaneous measurements. Keep in mind, even that is assuming that the NFL had a flawed process to begin with. If there is any time delay in either inspection at all, whether purposefully or accidentally, the thermodynamic effects would dimish almost entirely. Orr, Conor (July 29, 2015).

It concluded: "It is more probable than not that New England Patriots personnel participated in violations of the playing rules and were involved in a deliberate effort to circumvent the rules. A football or soccer ball valve is located on one end of the ball and is used to inflate or deflate the ball.In a series of text messages detailed in the report, McNally at one point refers to himself as "the deflator" in a text to Jastremski in May 2014.
