Further proof of this comes from the Steelers Texans back in 2002. Steelers out gained the Texans 422-47. Which is an insane difference. The final score however? Even crazier, it was a blowout victory for the Texans (24-6). Turnovers always have and always will correlate to more victories than total yards.

I’ll see your “correlation does not mean causation” and counter with a “an outlier mean an exception, not the rule”
I also just think generally you’re missing the point about the 400 yards argument. It’s not a “goal” as much as it’s a very prominent talking point about how our offense is… bad. Like 26th in the NFL in points per game both this year and last year bad
Edit: I just realized you cherry picked a game from over 20 years ago to make this argument lmao
