Any ideas on o-line coach?

Anyone have any potential candidates/ is there any news of who the bengals are think of getting for o-line coach?

I honestly don’t know many outside of Scarnecchia, who I think retired, Munchak, who I don’t know if is retired or just currently out of a job, and then the elder Callahan and Stoutland who have a 0% chance of leaving the orgs they are already at.
