How much were these balls supposedly deflated? If the normal inflation is 13 psi a drop in temperature could easily account for a small variation in pressure due to Charles Law ...temperature and pressure are directly related. I would think that a significant drop in pressure might affect the shape of the ball making its aerodynamic properties different. The deflated ball might be easier for a quarterback to grasp, but would it fly straight?

The balls are supposed to be within +/- 0.5 psi. They were 2 psi low. The temperature at game time was 51°F and the balls were inspected 2 hours before game time..............
