When you lose your mack linebacker in the middle of the season, and that player is of the caliber of Devin Bush, you don’t simply find replacements for them. The Pittsburgh Steelers can’t just go to the pedigreed athletic linebackers store and pick up another player in the same mold. Whatever they do going forward schematically and philosophically will necessarily have to be different because of his absence.
But the good news is that there are a variety of avenues that they can pursue, and it’s highly likely that they will employ multiple approaches in attempting to replace the several hundreds of snaps that will have been vacated due to Bush’s season-ending injury.
