Situations can unravel quickly in the NFL. Just a week ago, many were clamoring for rookie C Zach Frazier to be promoted to the starting role over Nate Herbig. But on the final day of practice at Saint Vincent College, Herbig sustained a season-ending shoulder injury. That obviously thrusts the rookie into the starting role but also creates a depth issue. Who is going to be the Steelers’ backup center?
In the first two preseason games, Herbig, Frazier, and Ryan McCollum were the only centers to log snaps. If you start to do the math on the 53-man roster, it is difficult to see McCollum carving out a spot for himself.
