If it wasn’t for his production the Cowboys would have been sitting home for the playoffs every season. His defenses haven’t been worth a crap until the last two seasons. He was on pace for over 6000 yards in 2020 until he was injured because he had crap for a defense. Stop hating and get real!
So it's all the defenses fault? Okay, no surprise there with the excuses.
PPG allowed by Dallas by year:
2016: 19 ppg
2017: 20 ppg
2018: 20 ppg
2019: 20 ppg
2020: 29 ppg
2021: 21 ppg
So outside of 2020, the Dallas defense has been very consistent in their points allowed and most would say that 20 ppg allowed is a good defense which should allow for offenses to help win the game.
That said, here is the Dallas ppg offensive average for the same years:
2016: 26 ppg
2017: 22 ppg
2018: 21 ppg
2019: 27 ppg
2020: 24 ppg
2021: 31 ppg
So while the defense has been consistent, it is actually the offense that hasn't been and is evident in 2017, 2018, and 2020 (Dak's injury season) that the defense wasn't the reason that Dallas didn't make the playoffs but rather the offense so while you want to remove all blame from Dak the fact is the Dak led offense has blame to be placed on it.
