I don't think there's much chance the Rams will use their first three picks on OL.
But the article did open my eyes to this: the only OL the Rams have signed for the 2022 season are Whitworth, Havenstein, Evans, Edwards, and Anchrum. And Anchrum is the only OL signed for 2023.
From that bit of news I am way less likely to believe that the Rams will trade Havs. I can't imagine Whit will play past 2021 which means in reality the Rams only have Havenstein, Evans, Edwards, and Anchrum signed for 2022.
So even if Evans and Anchrum develop into starters the Rams will still need one more starter for 2022 plus 4 (or 5?) more OL just to fill out the roster. It would surprise me if the Rams would make that situation even worse by trading Havs.
