Don't agree with this assessment. He's been very good in the vast majority of games played and a top tier CB's ability is fundamentally important in making a defense better.
As fans, we just tend to remember the less impressive moments and forget / not notice the large number of positive plays.
I agree - when he’s in the game - the defense is clearly better. The issue with Latt has been durability. He’s getting to the point now where he’s picking up nagging injuries and some major ones as well.
Unfortunately the trade window is usually pretty narrow. I think most agree that Latt is a massive part of the defense - but he’s getting older and getting injured and “allegedly” has some heat with Allen.
So as the wise Bill Belichick says - “it’s always better to trade a player a year early than a year late.”
