Again this emphasize:
Dak, even when he played amongst the worst football of any QB, in year 2 was the highest rated QB against the blitz. That’s how deceptive stats to prop him up have been. Teams blitz often times in desperation. If the blocking is top flight, which it has been for Dak since he got here, a blitz just exposes your backfield. And many average QBs have really good numbers against the blitz in limited situations as they tend to become less indecisive and make throws by instinct.
The reality is, Dak has always SUCKED against zone. Even when Amari got here, his numbers show up with Amari on man coverage, but Dak still sucked against zone and would simply fall back into a dink and dump QB, who would often times immediately just fall back to his check-down route. With a punishing RG that could wear down defenses, it worked. But now that those days are slowly going bye bye, teams simply just fall back into coverage and make Dak try and beat them with his arm.
Dak is SLOW processing the field, which is what has confused people. He can make the throws on his early reads when he knows where he is going, meaning the pressure is on the OC to get him reads quickly. But how often can you do that?
He’s always sucked against zone coverage and defenses were never really threatened by his arm. They just had to account heavily for the OL and RG, to the point that played so much man coverage.
