It's been around for awhile, so it's hardly cutting edge, but how do these NFL coaches get printouts of still images from the previous series so quickly on the sidelines? I'm watching Dallas-Washington right now, and I was reminded of this little bit of sideline technology that I've always wondered about.
You usually see the QB coaches/OCs looking at stills with the quarterbacks immediately following a series. It may seem silly, but I've always wondered about the logistics of how they get their hands on usable images in a matter of minutes. Is someone processing these, and shooting selected stills down to printers? Do the sideline coaches have to sort through dozens of them to find the ones to make their point?
