The Dolphins seem happy with Deiter, and they are trying to be careful with their cap after their FA splurge, so, I don't see this happening unless they can get a good bargain ... and why would Tretter do that? I suppose it is possible since the position wasn't addressed in the draft.

The Dolphins didn’t have much to work with in the draft, but none of their four draft picks went toward the offensive line. That leaves Michael Deiter — PFF’s 27th-highest-graded center in 2021 — stepping back into the starting center role with little competition.
Tretter would serve as a significant upgrade after earning seven consecutive 80.0-plus PFF pass-blocking grades. He would also walk into a Mike McDaniel offense that is fairly similar to the one Tretter has operated in with Cleveland the last few seasons. Both offenses ran outside zone at an above-average clip with a fair amount of power and counter mixed in.
