I think they need another CB. If White stays healthy he and Williams are a very good combo. But that's still IF. And while Curl and Lake can both play nickel CB, the CB depth otherwise is Tomlinson (unproven) and Durant and Kendrick who are really at this point 4th and 5th corners.
Interior OL- probably specifically a backup center- could also use addressing, though they do have Noteboom and McClendon as their top backups at OG/T.
Otherwise maybe they take advantage of the WR depth in this Draft. Maybe a TE?
DL could still use more depth.
