General manager Kevin Colbert tends to use free agency to fill obvious holes, allowing for a best-available approach to the draft. He might not have that luxury this year. The Worilds situation could go either way. We tentatively expect him to return if only because the AFC North champions lack any semblance of stability at outside linebacker without his presence. It should be easier for the Steelers to find common ground with Harrison, whose preference last summer was to play in Pittsburgh. In that scenario, Colbert could then address the secondary early in the draft.
