Few have seen inside Wilson’s facility where dozens of expert craftspeople meticulously put together a product whose design hasn’t changed for about a century.
Wilson worker Lindsey Kiene cuts leaf-shaped panels that are tapered at both ends. These will be sewn together to make the iconic oblong shape of the football, a key feature that reduces the ball’s wake and drag.

A football’s shape is not actually a ball in the spherical sense of the word, but a prolate spheroid: oblong, with pointed ends that make it easier to grip. This shape and the way air flows around it helps the football to travel great distances. When this happens, there’s a pressure difference between the front and back of the sphere which results in drag, the force that slows the ball down as it’s flying through the air. Golf ball manufacturers tackle this on spherical golf balls by dimpling the ball’s surface to help airflow stay attached longer, reducing drag, therefore letting the ball fly farther.Please be respectful of copyright.

While the air may not hug a football’s curves all the way across, airflow does remain attached past its apex, resulting in a minimal wake and less drag. On a baseball, the air only makes a connection on half the ball, creating more of a wake and drag., Pappalardo professor of mechanical engineering at MIT. Drag depends on the shape of the wake, which, in a football, can vary depending on such factors as its orientation through the air, the velocity at which its thrown, and surface roughness.
