I will say this. If they end up with the same rankings at the end of the season then it will be the first time in franchise history they were #1 in least points allowed.
You would think that, with such defense-minded Head Coaches, legendary ones in fact, they would have already accomplished this. However, they have been ranked #1 in least yards 4 times, most points scored 6 times, most yardage 8 times but never least points allowed. They were #2 in least points allowed 4 times.
They are currently ranked #1 in turnover differential. The only other time was 2021.
Here is an extremely interesting stat:
The Cowboys are ranked #2 in point differential. It would be the 14th time that the Cowboys would be ranked #1 or 32 in point differential. 11 of the previous 13 times, the Cowboys went to the NFC championship game. The only two times they didn't was in 1968 when they lost in the division round to the Browns and in 2021.
All of the stats produced over the past 62 seasons seem to indicate that the Cowboys had their opportunities to win the Super Bowl since the early 90's. Certainly, the teams in 2007, 2009, 2016 and 2021 had the best shots.
