The OP is a big Dak fan, so I'm not sure you understood his point. I believe that he was comparing Wentz to a bus driver, not Dak.
The truth is that Dak is not as developed as you would like to see a guy who has started 33 games in this league to be. If you watch the "All 22" (where you can see the entire field) you'll see that he missed on a ton of open receivers and even if he had hit on two or three of these plays it would have been a different game. I think you can chalk some of it up to rust, but his reads seemed slow. While the receivers weren't always open, they were open a lot more than they weren't. Dak simply did not see them or did not react quickly enough to catch them coming out of their breaks or even in stride. He often was fading back or dancing around, throwing off his back foot or on-the-run and seldom just planted and threw. This seriously affected his accuracy and ball placement. While he was under some pressure, he created bigger problems by frequently holding the ball too long or making the decision to run too late and getting sacked.
The narative that the Offense is too vanilla is wrong too. If getting that many open receivers is "vanilla", sign me up for that. If anything, the play design may be too complex for Dak for where his development is right now. Perhaps Linehan should go back to the cutdown playbook he used for Dak in 2016.
