Ever since Ryan Shazier’s burgeoning NFL career ended so suddenly and tragically, the Steelers have been searching for inside linebackers. Searching quite aggressively, I might add — first through free agency, then by relinquishing precious assets to move up 10 spots to draft Devin Bush, then by trade (Joe Schobert has yet to find another team, in case you were wondering). Here we are, five years later, and there’s still a void. The depth chart lists Myles Jack and Bush "OR" Robert Spillane at the inside linebacker positions. It’s not overly inspiring. Clearly, the Steelers value the position higher than many. Mike Tomlin has drafted an inside linebacker in the first round three times. At the moment, though, they lack a star and leader at the epicenter of their defense, where Jack Lambert and James Farrior roamed when this team was winning Super Bowls.
