If you want to know who are the most winning teams in the NFL you’re focus is going to be on the Dallas Cowboys and their Monday Night Football Opponent, the Chicago Bears. The Bears have won more games than any NFL team at 728 wins. The next closest is the Green Bay Packers at 695 wins. Teams that joined the NFL decades after these teams did would take many more decades of winning combined with futility in Chicago and Green Bay for an extended period of time.
What is more significant than the number of wins for the Bears is that they have the highest winning percentage in NFL History. The Dallas Cowboys are nipping at their heels. I have heard two different ways of calculating all time winning percentage in the NFL. One is to simply throw out the tie games. They are neither a win nor a loss. The other is that the tie games count as a half game.
The Bears all time record stands at 728 wins, 532 losses, and 42 tie games. If you use method number one, 728 divided by 1260 comes to 57.8% of all games played are Bears wins. If you use method number two you add the 42 games to the 1260 for 1302, and 21 wins to the 728 for 749. This gives a win of 57.5%.
Now let’s look at the Dallas Cowboys. 462 wins, 345 losses, and 6 ties. By method number one this puts the Cowboys at 57.2% of all games played are wins. By method number two add 6 games to the 807 for 813, and 3 wins to 462 for 465. This now calculates to 57.2% No difference.
