Thanksgiving for us Brits is a bit of an odd concept, its something not many or any of us really celebrate, but to our friends across the pond its a national holiday and a chance to spend a day with family. Football on thanksgiving goes back to 1876 and The University of Michigan. They became the first team in history to regularly host a thanksgiving game. The NFL adopted this tradition in 1920 under its former APFA name, 6 games were hosted that day.
As the years have gone on the NFL has developed its thanksgiving model and since 2006 three contests have regularly been held on Thanksgiving. The Detroit Lions and Dallas Cowboys are regular hosts, with the third a game picked by the NFL, normally a divisional game. This year the red hot Saints.
