PFF's Seth Galina breakdown of Joe Burrow 2020.

[*Synric*]

In reality the deep passing offense for the Bengals was hit by alot of different things.

#1 Joe was inconsistent with his deep ball
#2 His only vertical receiver AJ Green had an inconsistent year
#3 The Offense struggled to give deep passing opportunities
#4 Defenses were able to stop the run with their defensive front allowing them to run more cover 2/3

All of these were big factors in the deep passing numbers last season.
