Dec. 8, 1940: Washington went 9-2 in the regular season, Chicago 8-3. Washington and Chicago met in mid-November, with the former winning 7-3.
But when the two teams squared off on this day 72 years ago with the NFL championship on the line, the unthinkable -- and, thus far, unmatchable -- happened.
The Bears won 73-0. That's still the largest margin of victory in NFL history. As the story goes, Chicago coach George Halas was asked to run or pass for the final two PATs because too many footballs had been kicked into the stands.
