Here's an interesting video from Wired and Sports Illustrated on the future of the NFL game ball - can physics design a better football to improve the game? It suggests that a couple of small changes in the ball (weight, diameter) could make it into one you could throw 16 yards farther.

It'd be fun if the CFL adopted this first. "OUR BALLS ARE FASTER".
