The NFL has data on the air pressure of footballs from random games during the 2015 season, but by now it's doubtful those numbers will ever be made public.
"They did their own testing, they have results, but for whatever reason, they haven't shared them with any of us," Patriots owner Robert Kraft told reporters in Boca Raton, Fla. "And we actually requested that at the beginning of the season, they test every game throughout the league and do that, but they chose to do it their own way."
The longstanding theory here on the NFL's PSI testing: If the numbers make the Patriots look guilty, they get released.
