My memory may be failing me here (wouldn't be the first time), but it seems like we've been trying to build a defense with the draft, and reserving free agency more for the offense. Maybe if nothing else, they might try reversing that for a change.
I think last season was the beginning of the rebuild with replacing Thompson and Capers.
Maybe Gute's moves were a little more conservative than some would hope, but he had a good draft, and was at least in the running for Mack supposedly (he just didn't have the horses to compete with Chicago).
