I directly quoted you from the only posts I found so you couldn't say it was a misrepresentation. But good try on that charge...
So per your words, the 2nd half 2019 OL was "not bad" and "fine." And now as late additions we can add "not high caliber but
pretty solid," and "struggled against teams that could bring pressure."
Given the agreed upon 2019 OL 2nd half improvement, I do not buy that the dominant factor for Goff's failure to evolve was OL regression. I'll give you that theory for the 1st half 2019 OL. But that's it.
I think we all agree that the 2020 OL was even an improvement over the 2nd half 2019 OL. But to support that even further, I'll give the same 2020 PFF pass-blocking efficiency metric that I provided last Feb for the 2nd half 2019 OL which you quoted on the other board.
In 2020, the Rams OL was 6th. (You liked the metric last year so please spare me the contradictory argument on why it's so deficient now.)
Thus, what we have here is 1.5 years over the last 2 years where Goff failed to evolve despite having at least a "pretty solid," "not bad," and indeed "fine" OL to arguably a good OL in 2020.
