I think it will be a lot to ask Borom to be a starting RT right out of gate. Beyond 2021, maybe they can develop him to be that guy, but I would be shocked to see him in that spot to start the 2021 season.
So, my guess is to start 2021 would be:
Leno - Whitehair - Mustipher - Daniels - Jenkins
with Borom, Ifedi, and Bars as guys that can fill in multiple spots along the line for depth
Then, for 2022+
Jenkins - Whitehair - Mustipher - Daniels - Borom
Depth wise, maybe you look for an upgrade at Center for 2022 and then upgrading or finding a cheaper option than Ifedi as your swing tackle, etc
