Drops are high and receivers need to get in and out of their routes quicker. Focusing changes on those should help passing stats.
You could give QBs more time with some pass blocking assistance. Making faster smaller players less effective when facing larger guys with better pass blocking skill.
But not letting the receivers complete routes and them dropping the ball when wide open is what hurts my teams at seemingly at higher rates. The stutter is too slow and or receivers are slowed too much when jammed. Drops and knockdowns are too high still because of too tight of coverage and pressure
Getting QBs to make more accurate throws when facing pressure would take precedence to suggested changes to the actual pass blocking algorithms. As I think that would drive hurries up and sacks down.
The main thing I see is those passes that take longer to develop are seeing worse passing numbers. Whether it vs a cover or blitzing scheme the pressure is there and they are making what looks like too many bad decisions/ throws.
Poor defenders are too good at keeping tight enough coverage which is allowing for guys to make the plays that should not .
If you try to stop the run you can and if you try to stop the pass you can but I don’t see the need for talent cause the approaches are too powerful. Opening up deeper passes would make both approaches a bit harder to key on with less skillful players.
All my big passes have been on short and medium calls ......it almost that easy as long as the defense can’t key the run pass ratios too much. But it is a running/ chunk play version.
