Run It Up

They were instructed to inflate them to 12.5 psi. If they did that before the balls had reached equilibrium they would be underinflated before even touching the field. Which combined with the 1.8-1.9 psi drop attributed to the elements more than accounts for this.Here's the problem of the 1 psi rubbing theory: it assumes the pats rubbed their balls immediately before delivering to the refs at precicely 2:15 before kickoff. Does that make sense to anyone? If you were the equipment manager for the Pats, in charge of delivering game balls for the biggest game of the season, would you wait until the exact last minute?I wouldn't. I'd have it done a few days early to give Mr. Brady a chance to feel my balls in advance, just to make sure they were to his liking. That's just me though.Exactly, 1 psi is attributable to the weather (assume a 70dF locker room and 50dF field). The other psi (assuming mort is right and there is another psi) belichick attributes to the friction from the ball prep process which Tango rightly notes would need to raise the internal temp close to 90dF. Can a machine rubbing the exterior of the ball raise the internal temp to 90dF? No idea, but IMO THAT is the experiment that the NFL needs to run to prove/disprove this.Alternately, it appears that smart labs is making a case that a wet ball will expand and thus the psi will decrease in the process so there is that possibility as well, but BB clearly stated that their ball prep process raised the psi by 1 so that is where I would start if I were the nfl. But then gain, I probably would have contacted brady so wtf do I know (sarcasm alert)!Run It Up said:No, they were heated using friction, which the Pats openly admitted to, on Friday, last week.Tango said:Right! He corrected to say the temperature needed to be greater than a mere 90 degrees!So, to summarize, Patriots fans' latest theory is that the balls were inflated at Brady's grandmas house where she has the heat turned up to 95.Run It Up said:Welcome to yesterday, today NDT admitted he was wrong.Tango said:More than Nye says the Patriots science is way off:http://mweb.cbssports.com/nfl/eye-on-football/24997479/neil-degrasse-tyson-science-from-belichick-patriots-doesnt-add-upMorton Muffley said:So Bill Nye (alleged science guy but confirmed Seahawks fan) posted a video attempting to refute Belichick's explanation of the Deflategate hypothesis.
Unfortunately for Nye he makes two glaring mistakes that accidentally end up proving both Belichick AND tom Brady's points!
First, he says "imagine you are in a sweaty lockeroom that is 80dF and you inflate the footballs...then you move them to a field at 51dF" He then states that this change of approximately 30dF would result in "about a 6% change" [in psi] and that ZING "you'd be off by a factor of 2.5!" Here the 2.5 factor refers to a 2psi change being a 15% difference (6% x 2.5=15%). The problem is that he is making the same miscalculation that Neil deGrasse Tyson made (and recently retracted/corrected) of using gauge pressure instead of absolute pressure. Interestingly, when you use the correct pressure calcs, the 2 psi diff is actually a 7% diff and thus pretty close to the stated 6% diff that he can explain with the30dF temperature drop. Furthermore, it is VERY VERY far away from the "off by a factor of 2.5"...which is again is undoubtedly is the incorrect 15% that Tyson was first using.
Second, at the end of the video the timer goes off and he says "we just got this ball out of the fridge" at 51dF. He squeezes the ball and declares that it is "pretty much the same!!!" But since we know the ideal gas law has reduced the pressure in that ball by about 1.5psi we now have a debunker who is declaring that Tom Brady is correct in being unable to tell the impact that a small drop in psi has on a football.
Here is the video for any who care to watch Nye disprove everything he thought he was proving.

If the balls were rubbed more than an hour prior to ball inspection, they likely would have acclimated to room temp, which means that 1 psi is still unaccounted for.
