With Tom Brady and Peyton Manning still dissecting defenses, this weekend’s game between the Seattle Seahawks and Washington Redskins might not produce this year’s Super Bowl winner, but it may still be the key to the NFL’s future. Since their 3-6 start, the Redskins are on a seven-game winning streak, during which their already potent offense stabilized into one of the best in the league. Seattle, on its own five-game winning streak, has coalesced into arguably the best team in football. After outscheming the Chicago Bears en route to a dramatic overtime victory, Seattle pulled off one of the greatest three-game stretches in league history by bludgeoning the Cardinals, Bills, and 49ers, a stretch during which they outscored their opponents 150 to 30.

Among similar dominant stretches in NFL history, one that comes close was by the 1940 Chicago Bears, whose streak culminated in a 73-0 victory over the Redskins in the NFL Championship. That record offensive output followed totals of 47 and 31 points in the previous two weeks. The success was the direct result of a switch in offensive scheme by legendary Bears coach and owner George Halas, a switch that helped turn a 7-3 Bears loss to the Redskins earlier that season into the most lopsided championship game in any major professional sport. Halas, frustrated by his offense, turned to good friend and Stanford coach Clark Shaughnessy for help.

At the time, every NFL team ran the single wing offense, a shotgun-based attack with an unbalanced line where the ball was typically snapped directly to the tailback. Shaughnessy — first at the University of Chicago, where he and Halas became friends, and later at Stanford — had revived the old T-formation, which placed a quarterback directly behind the center. Shaughnessy updated the T to include a variety of motions and misdirection to buttress the running game and bolted on an all-new passing attack. The combination made the offense nearly unstoppable — at least in college. Even as late as 1940, most pro coaches viewed the T formation and its reliance on the quarterback making fakes and dropping back to pass as a bizarre gimmick. That is until Chicago ripped through the latter part of its schedule, and, with Sid Luckman as the prototype for a new era of "T-formation quarterbacks," built a dynasty.
