While the Pittsburgh Steelers should get inside linebacker Devin Bush back in 29021 after he missed most of the 2020 season with a knee injury, the rest of that position group now includes mostly unproven players battling for what could ultimately be as many as four other spots.

On Saturday, Steelers defensive coordinator Keith Butler didn’t sound too thrilled with what he observed from the team’s inside linebackers in the Hall of Fame Game.
