You lost me.........OP question was what position can we afford to wait and address in the 5th.
* First, we are not fixing much with a 5th rounder at any position.
* More times than not top run defending teams gets strong/high-level play from the LBer positions.

Here is an interesting site that breaks down individual stats by players and positions. It's interesting to see when we look at leaders of solo tacklers, assist tacklers and total tacklers, only a few DTs rank inside top 100. It's why I have said many times, fixing the run defense is just as much systemic as talent, maybe more so.
As for CB, notice the post stated we have starters for 2025, and we do. Now, if we want to address the replacement for starters, that's another topic. But addressing OP question, we are't desperate for 2025 CB other than replacing Lewis at the slot. That, as a rule, is generally a mid-late round player.
