PITTSBURGH — The chase goes on. The chase never ends.
The Steelers are still looking to replace Ryan Shazier, still looking for their next star — their next leader — in the middle of their defense.
You probably don't need me to tell you how much Mike Tomlin values the position, but I'll provide proof just in case: Tomlin has used his three highest picks, including his first pick as Steelers coach, on inside linebackers.
