You missed the point. Nobody cares about 1 stat by itself but its part of several factors (including wins) that have improved since 2018.
I think we were last in red zone TD's in 2019...horrible weakness. Now we are #1 through 12-13 games. Recognize it.
It's a huge whoopdie do. Can it improve? Yes but that also has to do with execution. Kirk dropped a TD and then didn't sell out on an excellent play call to get in. How many 3-1/4-1 tries has Drake and the IOL missed? Jeez man. If you can't get 1 yard, you aren't going to win close games. The only criticism I could give with that is find another way...get Streveler in there if the others can't execute.
"Improvement" depends on two things. One of them being how bad you were before. It's subjective. Is the offense better? Sure. Because it was really bad before.
It was good through week 9. We're now on week 14 and it's been poor through those games. If you want to use comparisons we can say it's much worse than it was the first half of the season.
