That said, not sure if we saw any reason beyond injury to not let Harrison start fulltime. If he's re-signed, he's not coming back as a back-up. Not even a rotational player. The only reason he's gone is cost, not his level of play.
If Harrison comes back, Chadman expects the Steelers would look at drafting an OLB because that shows little faith in Worilds.
The Steelers ought to draft an OLB regardless of whether Harrison comes back or not...and not just because of Worilds, but because of Woodley.
