There are a lot of name brand offenses out there, including Air Coryell, the West Coast Offense, and the Run and Shoot, which easily come to mind. As soon as you hear those names, you can picture the coaches and teams that have succeeded in those systems, guys like Don Coryell, Dan Fouts, Warren Moon, Bill Walsh, and Joe Montana. It often seems that the coaching geniuses are only found on the offense’s side of the ball.
On defense, there are a few name brand defenses, the 46 and the Tampa 2 are often talked about, for instance, for the success had by the Bears and the Buccaneers using those systems, but usually, defenses are described simply by their personnel groups, whether that be a 4-3 or a 3-4.
