Justin Herbert is one of the most criticized quarterbacks in the league despite being one of the most talented. That is what happens when the LA Chargers fail to have any team playoff success during Herbert's five-year tenure under center.
Emphasis on team playoff success.
As impactful as the quarterback position is, Herbert cannot line up on defense and keep other offenses at bay. He cannot line up at wide receiver and catch his own passes. And while Herbert has been far from perfect in his NFL career, the fact of the matter is that Herbert has elevated the Chargers much higher than other quarterbacks would in the same situation.
