Remember when posters here were so excited about Joshua Frazier after the draft that they thought he might start even though he wasn't even a starter in college? The Steelers already tried to replace McCullers as the backup inside, but Frazier flopped. I'm sure the Steelers will use another late draft pick or bring in a cheap free agent to try to push him off the roster again in 2019, but I doubt it's going to be a priority. McCullers is roster filler. It's not about potential at this point. It's about finding somebody better or leaving him in there as a reserve.
