most of those teams are scoring 6 / 7 / 17 points.
In 2021, Utah averaged 33 ppg. 2022 it was 36.
In 2023, only 1 team scored more than 36 on Utah the entire year. That was with Caleb, Penix and Nix on the schedule.
In 2023, Utah's points per game dropped to 23. The delta alone between having a real QB and Barnes / Johnson is almost enough to win some of the games you posted.
Utah hype is overplayed, I'll give you that. But it's all about the D and a weak schedule with no first round QBs, complemented by a known commodity at QB with empirical data to support.
