Best all-time NFL records

[RedinTexas]

****Updated through 2023-24 season****

The NFL began in 1920 and there are only 2 teams that remain from the original league, the Bears and the Cardinals. There have been 49 NFL teams that folded and all existing teams started in widely varying years. Because of that, teams have played wildly different quality of opponents and widely varying numbers of games. However, given all of that, here are the top 10 teams in all-time winning percentage:

1) Dallas Cowboys - 562-413-6 .576 (up .002 from last year)

2) Green Bay Packers - 799-598-38 .570 (down .001 from last year)

3) Baltimore Ravens - 256-194-1 .569 (up .008 from last year)

4) New England Patriots - 541-433-9 .555 (down .006 from last year)

5) Chicago Bears - 793-634-42 .556 (down .002 from last year)

6) Miami Dolphins - 496-399-4 .554 (up .002 from last year)

7) Kansas City Chiefs - 532-439-12 .547 (up .001 from last year and up one spot in these standings)

8) Minnesota Vikings - 523-435-11 .545 (down .007 from last year and down one spot in these standings)

9) San Francisco 49ers - 586-501-14 .539 (up .003 from last year)

10) Pittsburgh Steelers - 671-578-22 .537 (up .001 from last year)

The Bears and Packers both benefited from playing a lot of bad teams that folded shortly after founding. The Ravens were established in 1996, but were actually the Cleveland Browns, so they were a fully formed franchise from the very start and did not suffer the pains of an expansion team.

[I removed the speculation here about where we might finish in the next season. I'll come back and address that sometime before next season starts.]

I also broke down the numbers into the NFL divisions and found the following winning percentages:

1) NFC North .532 (unchanged)

2) AFC West .521 (down .001 from last year)

3) NFC East .520 (unchanged)

4) AFC East .508 (unchanged)

5) AFC North .508 (up .002 from last year)

6) NFC West .490 (up .001 from last year)

7) AFC South .484 (unchanged)

8) NFC South .442 (down .001 from last year)

The AFC West is also the only division in which every team is over .500. The NFC South is the only division in which every team is under .500.

Finally, I don't know whether this last comparison is meaningful, but in all-time records:

1) AFC .507 (unchanged)

2) NFC .502 (down .001 from last year)
