Another group based in Pittsburgh that includes brainiacs from Carnegie Mellon (somehow, I was admitted there and graduated with a degree a metallurgical engineering and materials sciences and a degree in engineering and public policy) claims that the conditions of the AFC title game would have caused a significant drop in air pressure.
“We took 12 brand new authentic NFL footballs and exposed them to the different elements they would have experienced throughout the game.” said Thomas Healy, founder of HeadSmart Labs and a masters student in mechanical engineering at Carnegie Mellon. “Out of the twelve footballs we tested, we found that on average, footballs dropped 1.8 PSI when being exposed to dropping temperatures and wet conditions.”
As explained by the group that conducted the simulation: “During testing, twelve brand new footballs were inflated to 12.5 PSI in a 75 degree Fahrenheit room. This was to imitate the indoor conditions where the referees would have tested the footballs 2 hours and 15 minutes before kickoff. The footballs were then moved to a 50 degree Fahrenheit environment to simulate the temperatures that were experienced throughout the game. In addition, the footballs were dampened to replicate the rainy conditions.”
It’s unclear whether the footballs were placed in a wet, 50-degree environment immediately after testing for a full 135 minutes before kickoff or whether they waited until just before kickoff to move the footballs to the simulated game conditions. It’s also unclear whether the various balls were exposed to the same external forces to which a dozen footballs used by an NFL offense would be exposed when rotated through the first half of a game. It’s also unclear whether re-testing of the footballs was done following the precise duration of the first half of the Colts-Patriots game.
