I don't know what you call it, but Benson, Doan, Kesselring, and Krebs are RFAs next season. Tuch is a UFA.
Keeping all these players probably requires moving other contracts (Greenway, Quinn, UPL, Byram/Power).
Moving on from Tuch means trading a contributor before the trade deadline, probably for draft picks because the cap space will be needed for the RFAs.
Roster decisions need to be made, whether they are considered a retool or rebuild.
