Then there’s the “twelfth ball theory”. If all 12 balls measured the same before the game and only 11 of 12 changed, all natural explanations go out the window. If they have the pregame psi’s your should see some sort of correlation in deflation amongst them all.
That’s a nice thought, but there are too many variables to consider. What was the original pressure in the “twelfth ball” and what was the final measured pressure. Was the ball in play or was it held in reserve? Was it ever on the game field or was it sitting in a game bag somewhere?
Only if 1) the 11/12 report is accurate, and 2) that all the balls were treated the same at all points in time. You should see a correlation in balls that were treated the same, with the same background.
