We used our new ANSYS AIM multiphysics simulation environment to do analysis on a football structure inflated to 12.5 psi and 10.5 psi — the two pressures in question. Then, we modeled the pressure points of a human hand on the exterior of a football that represents a throwing configuration and force. This allowed us to simulate the difference in deformation that a 2 psi pressure would create. The result? Not much. The difference in deformation between the two pressures was less than 1 mm, keeping the quarterback’s “squeeze” imprint at roughly 5 millimeters. The same applied to the receiver’s catch. In the world of players wearing tacky, rubberized football gloves, the “softness” difference is negligible.
