As is often case with pro football, some of the most-memorable offenses and defenses have been crowned with nicknames that capture their larger-than-life legends: Purple People Eaters, Steel Curtain, Greatest Show on Turf, Legion of Boom ... and of course, Buffalo's own K-Gun.

Debuted on Dec. 2, 1990 in the Bills' 30-23 victory over the Philadelphia Eagles, Buffalo's attack most often featured three receivers and a single running back, with QB Jim Kelly in a "shotgun" alignment a few yards behind the center.

Kelly engineered the offense, which for years was considered among the most dangerous in the NFL. The quarterback called his own plays and ran the offense without huddling. The result was a high-octane, all-cylinders onslaught that wore down opponents and helped Kelly, Thurman Thomas, Andre Reed, and James Lofton cement Hall of Fame legacies.

In a sign of the offensive fireworks that would follow for years to come, Kelly hit Lofton for a 63-yard strike just 45 seconds into the game, and finished the first quarter (!) a perfect 8-of-8 for 229 yards and three touchdowns. The K-Gun was born.
