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.

DECEMBER IS MAKE OR BREAK

A full one-third of our annual fundraising comes in this month alone. That’s risky, because a strong December means our newsroom is on the beat and reporting at full strength—but a weak one means budget cuts and hard choices ahead.

The December 31 deadline is closing in fast. To reach our $400,000 goal, we need readers who’ve never given before to join the ranks of MoJo donors. And we need our steadfast supporters to give again—any amount today.

Managing an independent, nonprofit newsroom is staggeringly hard. There’s no cushion in our budget—no backup revenue, no corporate safety net. We can’t afford to fall short, and we can’t rely on corporations or deep-pocketed interests to fund the fierce, investigative journalism Mother Jones exists to do.

That’s why we need you right now. Please chip in to help close the gap.
