Here is a deeper dive into advanced passing stats vs 2018 --

^^ what do these two advanced air yard stats tell us? His average depth of target is among the lowest in the NFL. Lots of screens, short passes, short crossing routes... Not throwing the ball down the field enough for explosive plays in the passing game. Look at those numbers compared to his last good season in 2018.
^^what do these advanced accuracy stats tell us? He is pretty accurate when throwing the ball. This has always been the case with Goff and his arm talent. There have been twice as many passes dropped this year vs 2018, and there have big some big drops this year for sure. But how would the bad throw% numbers change when his average completed depth of target increases beyond 5.4yards? Safe to assume they go down if he was throwing the ball down the field more, just like in 2018. But overall, the accuracy stats seem solid.
^^what do these advanced pressure stats tell us? In 2020 Goff has been pressured much less than he was in 2018. He's been pressured the 4th least amount of all QBs this season, but he's been blitzed the 7th highest in the NFL. Think about that, 7th highest amount of blitzes but the 30th QB in amount of pressure taken. That tells me something about the oline and how McVay has changed his scheme to keep Goff away from pressure. How about pocket time? #9 in the NFL in time given in the pocket, and only 1/10th of a second less than he had in 2018 when he had the most pocket time in the NFL at 2.6 seconds per snap. This has lead to less sacks this year through 10 weeks. He has only been sacked 13 times this year through 10 weeks where he took 33 in 2018.
So he's been pressured less this year, has taken less sacks, has about the same time in the pocket to throw. To me no one can blame his play on the oline or the pressure after looking at this. His accuracy is solid this year but he has had to battle through more drops than in 2018. However his average depth of target is much less and shows he's not throwing the ball down the field nearly as much. To me given the way the running game has played (8th rated rushing attack in the NFL) and clearly above shows how well the oline and McVay are playing to keep Goff away from pressure, he should be playing much better.
