Article: Saints offense refuses to use play-action, motion like the rest of the NFL

Oof. I still think after watching a lot of film that he's already determined to check it down to Kamara before the ball is even snapped. He's missing too many intermediate and deep reads and doesn't seem interested in letting the routes developed. If he doesn't trust his receivers, then he either needs to work with them or he needs to quit. You're not going to win over teammates like that when we know for a fact that the other two QBs who are suiting up on gameday both trust the receivers, one guy maybe just a little too much.
It’s tough to watch, especially since he was supposedly ready to play in our system. We even brought in Gruden to help curate the best calls for what Carr does well.

The terrible OL play isn’t his fault, but Carr doesn’t consistently get it done when the protection is there, often checking down as a first option as you pointed out. He had his best game against the Colts because it was also the game where he faced the least pressure, lean on him just a little and our offense is done.
