My biggest hope is that the Cardinals can head to the draft without glaring holes on the roster. That would be a great start.
Because of that, I think it is ok to exit FA with a DL group of Jones, Nichols, Robinson, Stills, Lopez and Collier. That leaves you the option of draft a DT 3rd round or higher and just have to figure out where to get one extra roster spot.
EDGE is the biggest "issue" on the roster. There just isn't much talent, and the FA class looks pretty crappy.
OL is interesting. I do think there will be some answers in FA depending on what the Cardinals want to do. I think you can start the season with Adams as a starter, but you need to have the other G spot and RT figured out to do so.
ILB is scary because I have no idea what they will do. I don't think Monti and Gannon "prioritize" it in the way Keim did. The contracts for White and Wilson along with the invested draft equity seem to support that. (EDIT: I have liked the current approach towards the ILB position. the scary part would be a change to that approach.)
I have no idea about WR. I don't see a bunch of options that fill the need the Cardinals have.
