Why did the Bengals fail to address the roster mid season?

[Benton]

Honestly, I haven't paid that much attention to other teams this year, but I'm guessing the difference is those teams were a player or two off from what the organization felt like they needed. The Bengals (largely due to coaching) were more than just a linebacker away from being solid. I mean, we could've added Tate, sure, but would he have done much that someone here wasn't already doing? I don't think so.
