I do think the Jets need to get a legit offensive mind ASAP.
I am actually okay with Bates. He has had some good successes and worked with good people. He's not great, but he's not awful. I've seen some good things and some bad things over the first handful of games. They could certainly upgrade but I think they can win games and be successful with him.
The problem remains the draft, IMO. Look at 2017--ArDarius Stewart. Godwin goes a few picks later, Golladay right after that. Chad Hansen--George Kittle goes right after, and instead of taking Kittle they take Leggett a few picks after that. Or they could have had Marlon Mack. Dylan Donohue is terrible and gone, like Hansen. Jeremy Clark sucks. Derrick Jones sucks. Adams and Maye were good picks, McGuire may be a good pick.
2016--god, 2016. Darron Lee, super mediocre. Hackenberg, terrible. Jordan Jenkins, pretty good pick. Burris sucks, Shell is I guess okay, Edwards is fine if you like drafting punters you probably could have signed as UDFAs, Peake is only okay because he was a 7th rounder.
2015--6 picks and only Leonard Williams is still on the roster.
2014--This was the John Idzik draft which was possibly the worst any team has ever had. 12 picks, and they're left with Quincy Enunwa and a backup lineman in Dakota Dozier. Everyone else flamed out. It was horrible. Set the team back a few years at least.
So, if you focus just on Idzik, they probably could have had a couple more skill players and maybe two more guys that can actually play on the offensive line. Maybe another LB or DL or something. Instead, jack shit. And the same for the Idzik draft; had he not made a bunch of weird picks, the Jets could be so much better off.
Obviously this is in hindsight, but so many of those picks at the time were viewed as reaches, or, "Why pick X when much more highly-regarded Y is still there?" types of picks. And to Mac's credit, he has done a good job, generally, moving picks--Sheldon Richardson for Kearse and a pick used to then acquire the Darnold pick, Pryor into what's his face, Henry Anderson for a seventh, etc. But the point remains, they've done an awful job drafting. They're also apparently scared to spend money on free agents.
