From what I have seen of Smith at LG, I prefer him at LT.
Steele is not going anywhere in 2023. He is a restricted free agent and the Cowboys will definitely tender him at 2nd or even 1st round level. They should consider offering him an extension depending on how his rehab is going. From what we have heard of Steele is he is a hard worker so I think he will do what he has to to come back as strong or stronger than what he was.
McGovern will mostly like sign elsewhere. But I think they can replace him with someone else. I like him, but he is not a critical piece of the puzzle. Maybe they can find a free agent OG to replace him.
The Cowboys have a big decision to make with Tyron next year. 2023 is the last year of his contract (2024 is voided). If they plan on leaving Tyler Smith at LT then they won't need Tyron in 2023. But how to you cut a guy wo has been a stud for you for so many years. Maybe he decides to retire on his own.
I don't think OL is urgent. Expect Waletzko and Ball to come back better (remember, McGovern was pretty awful his first two years too) next year. They have some guys on the practice squad they can promote to fill backup roles.
Not that I wouldn't draft OL, but if I had a choice between DT, CB, and OL, I would go for the DT.
