Cowboys Could Finish 50 Seasons with Best All-Time Winning Percentage
For a brief time during the 2008 season, the Cowboys had the
best all-time winning percentage among NFL franchises. By the start of the 2009
season, however, the Cowboys had fallen to third. Here is a look:
Prior to the 2009 season:
1. Miami Dolphins: 380-272-4 (.583)
2. Chicago Bears: 686-499-42 (.579)
3. Dallas Cowboys: 423-309-6 (.578)
Since then, the Cowboys have gone 8-3, while the Dolphins have gone 5-6 and
the Bears have gone 4-7. The result is that the Cowboys are closing in on the #1
Winning Percentages Through Week 12:
1. Miami Dolphins: 385-278-4 (.581)
2. Dallas Cowboys: 431-312-6 (.580)
3. Chicago Bears: 690-505-42 (.577)
It would be something else if the Cowboys could complete their 50th season as
the NFL’s winningest franchise, and there is now a good chance of that
happening. Here are the possibilities (excluding ties, because I am too
dumb/lazy/dumb to calculate those):
(a) If the Dolphins win all five of their remaining games, Miami would remain
at the #1 spot with a winning percentage of 58.3832%. The best the Cowboys can
do by winning all five of their remaining games is finish with a percentage of
(b) If the Dolphins win four of their last five (58.2335%), the Cowboys have
to win all five of their games to earn the #1 spot (58.2888% with five wins).
(c) If the Dolphins win three of their last five (58.0838%), the Cowboys have
to win at least four of their five games (58.1551% with four wins).
(d) If the Dolphins win two of their last five (57.9341%), the Cowboys have
to win at least three of their five games (58.0214% with three wins).
(e) If the Dolphins win one of their last five (57.7844%), the Cowboys have
to win at least two of their five games (57.8877% with two wins).
(f) If the Dolphins fail to win another game (57.6347%), the Cowboys have to
win one of their final five games (57.7540% with one win).
It is possible for the Bears to surpass the Cowboys once again, but it would
take a huge turnaround in Chicago for that to happen.
