"The offensive player knows where he's supposed to run, where he's supposed to stop, where he's supposed to cut, where he's supposed to block, where the defensive player is trying to figure that out. And he figured it out why? Through watching what players do and also from the hours and hours of tape that he might have watched. Because a lot of times they watch a lot of videotapes, and I mean, like, film. They were like video."
