Obscure Fact: Cowboys Briefly Had the All-Time Best Winning Percentage
This is an unknown fact that I did not know until I stumbled upon it by accident: four weeks ago, the Cowboys were the all-time winningest franchise in NFL history in terms of winning percentage. Since going 1-3 in the past month, the Cowboys have slipped back to second in this category behind Chicago and just ahead of Miami. Below are the numbers.
Before the 2008 Season
Dallas entered the 2008 regular season with a .578 winning percentage, calculated by dividing the total number of wins by the total number of wins and losses combined (and discarding ties). Miami edged Chicago for the best record with a winning percentage of just over .580.
1. Miami: 369 wins, 267 losses, 4 ties (.58019 winning percentage)
2. Chicago: 677 wins, 491 losses, 42 ties (.57962 winning percentage)
3. Dallas: 414 wins, 302 losses, 6 ties (.578 winning percentage)
After Week 3
After three games, Dallas had a 3-0 record, while Chicago and Miami stood at 1-2 each. The Cowboys’ all-time winning percentage improved to .580, while the Bears and Dolphins were tied at .579 (the Dolphins actually had a very slight edge). Here are the records at that point:
1. Dallas: 417 wins, 302 losses, 6 ties (.580 winning percentage)
2. Miami: 370 wins, 269 losses, 4 ties (.57903 winning percentage)
3. Chicago: 678 wins, 493 losses, 42 ties (.57899 winning percentage)
Before Week 8
By going 1-3 in their past four games, the Cowboys have slipped back to second in this category, while Chicago has taken the lead.
1. Chicago: 681 wins, 494 losses, 42 ties (.580 winning percentage)
2. Dallas: 418 wins, 305 losses, 6 ties (.57815 winning percentage)
3. Miami: 371 wins, 271 losses, 4 ties (.57788 winning percentage)
