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?
Another thing to consider is that after the balls were reinflated back to spec at halftime.....presumably in the same locker room, they reportedly remained in spec at games end.
