It’s my belief that there are, at any one time, maybe two offensive lines that you’d consider “better than average” and that the vast majority of OLs are middling-to-poor.
I think you're a smart guy, but to limit offensive line ratings to either a 1, 2, or 3 score bunches the jets into the bottom 15 teams who could have a rating from 0 to 33% on your scale, but probably more like 0 to 50% with the Chiefs above 95% and the 2's 50 to 95%. If you expanded the ratings criteria, say 1 to 10, Chiefs would be a 10 or 100%, on the curve, and the Jets maybe low 20's?
Pat Mahomes plays behind what you’d consider the best left-to-right OL in football, scrambles a hell of a lot, and his time to throw is still a lot lower than Zach Wilson’s. Wilson’s problem is that he’s not seeing his first read, bailing on the pocket, and making life worse for everyone.
Apples and Oranges. Mahomes sat a year with learning from an Offensive Genius and behind, I think, a very capable Quarterback in Alex Smith (he would be a 3 in your estimation. And I'm pretty sure they had a good offensive line back then too. Repetition breeds confidence, muscle memory, etc.
Mahomes has played in 64 games including numerous playoffs and 2 Super Bowls to Zach's 14 behind an atrocious offensive line, a new coordinator installing a foreign offensive system to Zach, and a <who's who of receivers.
Even on the play designs Warner is complaining about, it appears as though the receivers are pulling up because they know they’re not getting the ball. The INT where everyone is killing Moore, Garrett Wilson is running wide open twenty yards down the field but Zach—well-protected on the play— doesn’t even look at him.
Missed open receivers happens EVERY game. Ask Russell Wilson, who has 160+ games, 16 playoff games and a Super Bowl ring, and apparently millions of viewers.
I didn't notice the purported poor route running by Moore during the game but after watching video explanations, agree if Moore pulled the defender into the end zone as supposedly drawn up, they would have had the ball inside the 5. End result we won the game but that "catch" might have changed the outcome in a Multi-Verse sort of way.
In the old "what have you done for me lately": 10/12, 130 yards, 2 TD drives works for me.
