continuity matters above all on an OL

You can have 5 decent OL and of they have familiarity and consistent experience with each other the result will likely collectively perform greater than the sum of their parts.

They need to replace liabilities on the OL for sure. Evans, Kolone, etc. have really hurt them when they've played. Havenstein is not a star but, in a train weck of a season, he has actually done alright (22nd among 77 OT according to PFF). A couple 2023 upgrades on the OL and simple better health can pay big dividends.
