You can pretty much play a name game of "Jets Starting CB or automated Madden draft pick name" and I don't know if I would pass at this point.
I don't know how our cornerbacks are going to stop anyone this year. Our pass rush could be decent if Quinnen is a monster, but we still don't have edge rushers unless Polite is better than he looks.
I think the Jets are going to play a lot of high-scoring games this year. Darnold is going to have to throw a ton to keep us in games. It's pretty comical the Week 1 over/under is 38.5 right now. Even though the Bills receivers suck, John Brown will be able to burn every one of our CBs. Hopefully Zay Jones has his normal allotment of drops.
I haven't been able to watch the preseason that closely, so I'll trust your evaluations on these cornerbacks. Roberts is a decent #3 who can fake it as a #2. Poole can be OK in the slot. Neither is great, even in those roles, but at least they're NFL players. I have no idea if any of these other players are even NFL players.
And Trumaine Johnson was bad last year, and he's already injured. So I have very little faith in him. However, he's at least shown to be an NFL-caliber player before, and maybe he can do it again.
