To me it’s play calling, sure, but his actual play design is SO often terrible. Receivers aren’t schemed open. We see everyone running horizontal routes or all running vertical routes. He doesn’t use space to create space. There are so often receivers in the same space, such that none of them is/are open. RB’s are swarmed in the backfield because they absolutely KNOW when we’re running the ball... Nagy is an absolute fraud.
I feel for Montgomery, Robinson and Mooney, all guys with talent and who deserve better. Kmet, as well, for that matter. Nagy is not just an awful play caller, he’s a TERRIBLE play designer.
