You must not have been here yet when I turned over a new leaf and said I would not criticize PFF. I embrace them and their Dear Leader fully as experts and hold their opinions as fact! LONG LIVE CHRIS COLLINSWORTH!
Ok, that last bit was maybe an overstatement. But I did make a resolution to stop ragging on PFF, and I have kept to it. And I do find some of their analytics interesting, though I still have some issues with their grading. But I don't attack PFF anymore, and I am willing to engage in a PFF-driven discussion. And you said I could never change.

(I made no such resolution about Jay, much to the dismay of many.)
And I will take as fact that Lattimore might be the 8th worst CB in the league. I don't find that hard to believe at all. He's really struggling.
Though, I'm honestly not entirely sure what you're asking. My point is, at the moment, there are REALLY few options with healthy players on the team. Mikey S. did not practice because of a knee, Amos didn't practice last week, Jones is on IR.
The only thing I can think of them doing, and they might do soon, is move Mikey S. outside, Noah I. into the slot and bench Lattimore. That's about the only option because they don't have another healthy CB on the roster.
When Jones comes back, assuming the other 3 CBs are somewhat healthy, they might have more options.
But for now, I get the "how much worse could it get." But in order to change you need somebody to change to, and I don't even know if that exists.
