What positions would you sacrifice for better OL?

[*ochocincos*]

We all know (and have known for years) that the OL needs upgraded.
I think we can all agree that ideally we'd like for the OL to get upgraded with proven vet FAs.
With that said, the Bengals don't have unlimited cap and don't really ever do restructures.
They have the following non-OL positions with a starter either hitting FA or just flat out needing upgraded:
- TE
- CB
- S
- DT

So what position(s) are you ok with allowing to be addressed with cheaper FAs (under $5 mill) and/or draft picks so that the team can better address OL in the draft?
