The Pittsburgh Steelers entered this league year with nearly a couple dozen players scheduled to hit unrestricted free agency. They ended up retaining five of those unrestricted free agents, but did not tender their one restricted free agent, who signed elsewhere.
Pittsburgh also added help from outside of the organization at tight end, tackle, linebacker, and the defensive line, but suffered several free agency losses, chiefly at cornerback and linebacker, and suffered yet another key retirement in the process. There were no significant player releases, and no contracts were restructured. They still have six unrestricted free agents who remain unsigned.
