I've made my thoughts on Hayden kind of clear over the last few years. Just don't see how he gets the PT he does because he provides almost nothing. Can't rush the passer and really isn't very good against the run. But I don't have a huge problem with him in a backup role if he wins the job at his salary. My issue was more with the team giving him starter snaps.
With the exception of Lawrence, Gregory, and Crawford (Jack) the whole DLine can be questioned.
It's not the worse DLine but it can easily be upgraded.
We have some potential on the d-line, just think the middle is in need of a huge upgrade. Hayden offers almost nothing.
Though purely optimistic, I'd love to see one of the Jets d-line (Wilk/Harrison) Next to Crawford.
Also apart from who you've mentioned, like what I've seen from Irving.
