To those of us for whom the nuances of professional football tactics are a bit of a mystery, there was one question looming over New England Patriots quarterback Tom Brady’s surreal Ballghazi press conference yesterday that went unanswered: What’s so great, in theory, about a deflated football? Seems like, if anything, an under-inflated ball would be less aerodynamic?

Turns out, the potential benefit is all about grippiness. From Fox Sports:

John Eric Goff, professor of physics at Lynchburg College in Virginia and author of “Gold Medal Physics: The Science of Sports,” told FoxNews.com that the league-mandated PSI range is ideal for playing football. “If, however, there’s rain or snow or something else happening, that would make the ball a bit slicker, so having a bit less pressure in the ball makes it easier to squeeze and the grip improves,” he added.
