It's a Grandiron

From Wikipedia:
When the St. Louis Rams lost on December 4, 2005, the Seahawks clinched their second straight NFC West title after playing only 11 games.
On December 5, 2005, the Seahawks shut out the Philadelphia Eagles 42-0 with three defensive touchdowns (two interceptions, one fumble return) to tie the largest margin of victory mark in Monday Night Football history and set the mark for the greatest margin of victory in an MNF shutout, as well as setting the NFL record for scoring the most points with under 200 yards of offense. A fourth interception return by Michael Boulware fell just short of tying another Seahawks NFL record of four defensive scores in a single game, set during a 45-0 victory over the Kansas City Chiefs in 1984. When the game had finished, the Seahawks had handed the Eagles their 3rd worst defeat in team history (Seattle also handed the Eagles their 5th worst defeat since 1998, the last time the Seahawks played in Philadelphia).
