Next we need to look at the team that joined the NFL one year after the Cowboys, the Vikings. Their all time record is 426-355-9. That is 22 games behind the Cowboys, but more importantly a 16-0 season would still put them 6 games behind the Cowboys pace.
How about the other 10 teams that came after the Cowboys? Let’s go from least number of seasons to the most. The Texans are 77-99-0. This year will be their 12th season in the NFL. At the conclusion of the Cowboys 11th seasons they too had 77 wins, but in fewer games. The Texans have played all of their seasons on the 16 games schedule. The Cowboys first year was 12 games, the next 10 were 14 games. That means they reached 77 wins in 24 fewer games.
The Super Bowl Champion Ravens are 150-121-1 in 17 seasons. After 17 seasons the Cowboys were 137-93-6. The represents 36 fewer games than the Ravens due to the 12 and 14 game seasons the Cowboys had played. If you add 1977′s 14 games and 1978′s 16 games this adds 30 games and brings the Cowboys total in the same span to 161-99-6. Add the next 6 games for an equal schedule and the Cowboys were 166-100-6. A full 16 games ahead of the Ravens pace.
The Ravens pace far exceeds the two teams that came the year before them. The Panthers are 132-156, and the Jaguars are 140-148. If the Cowboys are ahead of the Ravens then they are clearly ahead of these two teams as well.After 18 seasons the Cowboys were 149-95-6. That is 9 games ahead of the Jaguars and 17 ahead of the Panthers in 38 fewer games. In the next 38 games the Cowboys were 28-10. In other words, 37 and 45 games ahead of the pace of those two teams.
From there we turn to the Seahawks at 280-300, and the Buccaneers at 229-350-1. Each of those teams is entering their 39th NFL season. At the end of the Cowboys 38th season they were 334-222-6. So they have played 18 fewer games in the same number of seasons yet lead the Seahawks by 54 games and the Buccaneers by 105. Just for giggles, the Cowboys next 18 games they were 12-6. That brings it to 66 and 117 at the same pace.
