Bouchette posted that piece a while ago, but I have a hard time believing that the Steelers will go into the season with that line. I would like to see Starks return and battle it out with Adams and Gilbert. If he leaves, I think a developmental rookie for depth at OT is a need, but not a premium pick.
I think Beachum is best suited for a Trai Essex role. I doubt they go into the season with him as the only option at LG. I think either Foster or Colon will return. Maybe Colon takes a pay cut. I doubt he could find the salary he has with the Steelers on the open market. I suspect that Foster will end up in AZ. If they both leave, then I think a midround guard becomes a need.
