Our ruling

Belichick said that moving the footballs from indoors to outdoors could explain the loss of about 1.5 pounds per square inch of pressure. Experimental and mathematical results are in that ballpark. Lab tests said air temperature alone could bring down the pressure by 1.1 pounds. The ideal gas law predicted a 1 pound loss. The rain that day would explain at least another 0.2 pound shift and possibly as much as 0.7.

We lack firm numbers on the actual pressure drop in the Patriots footballs, as well as precise information on the starting and ending temperatures. Within the limits of what the physics alone can tell us at this point, the math gets us pretty close to what Belichick said.

With allowances for the uncertain data, we rate the claim Mostly True.
