I would be perfectly happy if they went O line in the first 2 rounds, just like they did on defense this year. I am nowhere as concerned about the WR and DB groups as I am the O Line and complete lack of depth.
Rivera & McDermitt will coach up the DB's, especially with the stout front 7. Josh Norman can be a legitimately good starter I think
Prohl has gotten this WR group to look legit, even if the national narrative is to continue to poo on them.
The O Line is still a major question mark even with signing Wharton. Byron Bell is a great effort guy, but him playing average is a major accomplishment. Silatolu is inconsistent at best, and Gross is still good but not dominant. Garry Williams is a major question mark, too. Kalil is the only above average player on the O Line right now (maybe Gross).
That being said, Cam's mobility and good play calling can mask some of that deficiency. I just can't see this group being a dominant run-blocking unit, no matter how much Shula wants it to be.
