Yes, I think you are on to something. The window for AD and Stafford is closing, for Kupp I'm not sure yet. On the other side they will have their first round pick and plenty of money to sign FAs.
I think we'll see some combination of draft and free agents to upgrade their weaker areas. Edge rusher and corner back are high on my list. Then Left Tackle and running back. Finally, if we can help our safety room I think it would be warranted.
