Pittsburgh Steelers inside linebackers “evolve.”
Pittsburgh’s first player at the position was Jack Lambert, who “evolved” from a middle linebacker to an inside linebacker. Both Mark Barron and Miles Killebrew the Steelers last two free agent signings at the position started as safeties and “evolved” into inside linebackers.
In between, Huey Richardson was drafted and listed as an inside linebacker, but in 2014 the Steelers Media Guide suddenly started listing him as a defensive end.* So this Steelers most infamous 1st round bust managed to evolve at his position 22 years after Bill Cowher traded Huey Richardson in a fire sale.
Injuries and COVID-19 infections forced the Steelers to evolve on the fly at inside linebacker multiple times in 2020. But how will that unpleasant experience impact their plans in the 2021 NFL Draft.

Steelers Depth Chart at Inside Linebacker: The Starters
Who, other than Ben Roethlisberger, was the Steelers most indispensable player in 2020? Prior to the season, the Athletic’s Mark Kaboly argued it was Devin Bush.
- What happens if Devin Bush goes down?
The ominous answer was that Robert Spillane would have to play. He did. And he played well. In the battle of the undefeated he Derrick Henry at the goal line play that could ONLY have reminded his position coach Jerry Olsavsky of a similar stop he made of Christian Okoye back in 1989. The next week he took one of Lamarr Jackson’s passes to the house providing Pittsburgh with a critical point differential.
Robert Spillane might not be a superstar in the making, but his play was solid enough to convince the Steelers to cut Vince Williams, the starter opposite him.
Devin Bush’s sophomore season only lasted 5 games, but that was long enough to register 2 half sacks, pat down 3 passes and log 3 quarterback hits.
Steelers Depth Cart at Inside Linebacker: The Backups
The story for the Steelers here changed dramatically for the better last week when Vince Williams announced he was rejecting other offers and returning to Pittsburgh on a reduced salary. While that may seem odd, as few if any Steelers have ever done that, Vince Williams will likely slide into the role he played earlier in his career as part-time starter.
In 14 games during 2020, Vince Williams sacked the quarterback 3 times, recovered 2 fumbles and generally laid in the wood when it needed to be laid in.
The Steelers also signed Miles Killebrew, who as mentioned above, began his career as a safety before moving to inside linebacker. Killebrew played for 5 years in Detroit, appearing in 78 games but only starting 5. He did log two interceptions at safety early in his career, and could become a “Dime Linebacker” that the Steelers have been seeking.
The Steelers also have Marcus Allen, yet another converted Safety who started two games this past season, registering 2 tackles for losses and hitting the quarterback twice while struggling against the run.
Finally, Ulysees Gilbert III the Steelers 3rd 6th round pick in the 2019 NFL Draft who has only appeared in 11 games.
Steelers Draft Needs @ Inside Linebacker in 2021
The Steelers are betwixed and between at inside linebacker.
On the one hand, they’re blessed with 1 up and coming starter and two starter capable players alongside him. That’s a good thing.
- But both Spillane and Williams are upgradeable, and Pittsburgh has little proven depth behind them.
Miles Killebrew came out of the free agent bargain bin, Marcus Allens’ play there was hardly convincing and Ulysees Gilbert has done little more than get injured during his time in Pittsburgh. Given that the Steelers draft needs at Inside Linebacker must be considered Moderate-High.
*The plan was to use Richardson at inside linebacker and defensive end. He played there in his strong preseason debut, but his career imploded immediately after that. Now you’re ready if you get “Steelers Draft Busts” as a Final Jeopardy category – so get back to work.
