We may have a lot of players signed, but our defensive line has a lot of guys at various spots in the process of aging out of their prime - Lawrence (33), Williams (31), Reed (33), Nwosu (29). And many of our free agency departures are notably concentrated in the back seven (Bryant, Woolen, Jobe, Thomas, Okada) along with Walker and Rashid (both of whom could well be re-signed) and Boye Mafe.
We're going to have a lot of holes to fill, and not a lot of draft picks to do it unless we trade down. We do have some promising depth to try out, like Mills and Horton.
I would expect more than one significant free agency addition.
