Monday Night Football - 1990 to Present
Maybe you should have looked at some historical data before you started getting too full of yourself. Between 1990 and 2004, there were ZERO games scheduled on MNF in cold weather markets the last 3 weeks of the season. In 2005, the NFL scheduled 2 to end the season, Packers @ Ravens and Patriots @ Jets but both involved teams that play outdoors in cold weather markets. Then there were no more until the Bears ended the 2008 season with the Packers and 2009 season with the Vikings. The 2009 season was the first time in more than 20 years that the NFL had a dome team playing a night game outdoors in a cold weather market on MNF in the last 3 weeks of the season.
Sunday Night Football is excluded since the league allows that game to be flexed from the best matchups in week 7 and beyond each year and isn't final when the league posts the schedule each April.
So out of the 60 MNF games in the last 3 weeks of the season between 1990-2010, only 4 have been played in cold weather markets at night in the last 3 weeks of the season. I would call a 93.4% scheduling rate a rule of thumb.
