He's not completely wrong. JDB's idea of "fixing" the passing game was to "nerf" the passing game to oblivion. And that goes for ALL phases of the passing game. Pitching, catching, and blocking.
But I'm anxiously awaiting those monthly UI updates...

Here is what I know about passing from years of playing and following the forums closely.

Passing accuracy is a downward facing parabola so that the display accuracy is just a guide to the functional accuracy. The intercept of this parabola I assume is 50 because any accuracy below 50 and a quarterback will not complete a pass.

Accuracy as a skill means how well the quarterback places the ball. A quarterback not under pressure and with perfect play knowledge with 100 accuracy will have perfect accuracy. How much play knowledge and being under pressure and crowd noise affect a quarterback accuracy is unknown but the accuracy equation is out there.

But because QBs place the ball extremely accurately receivers were nerfed in version 4.4 (which lasted about two weeks before 4.5 was released). This nerf increased the drop rate for passes so many yards beyond the line of scrimmage so that the completion rate down field better mirrored medium and long passes in the nfl. It is what it is.

But this nerf exposes many other problems with the passing game.

The way receivers and coverage works is that cornerbacks roll B&R to prevent the receivers from accelerating to max speed. Otherwise slow corners got cooked always. This isn't really a bad thing but it's over powered. It keeps receivers from getting much separation and leads to a lot of knock downs because otherwise quarterback would complete every pass because of the above.

This next part is an assumption backed by a lot of data analysis.

The coverage code exposed what was an obvious change to pass block timing on long passes in 4.6. It's clear that pass blocking degrades overtime as the defender wins. This is fine. But the timing of this degrading is immediate for long passes. Linemen stop blocking on the snap and let defenses run through them. At the same time the coverage code holds receivers within ten yards of the line of scrimmage so the defender gets to the quarterback before the receiver gets in a route. Making long passes unusable.

Can’t be true. If you know that then JDB knows that, meaning he has just not fixed it in years. Sounds way too disregarding, almost negligible.

Unless…..

He hasn't fixed any of these things in years.
