While the Pittsburgh Steelers have made major apparent concessions in recent years with respect to giving rookies and young players opportunities to get on the field and contribute, the one area in which they have not made exceptions is for young players who are not on the practice squad.
That is one of the major reasons that 2018 rookies Marcus Allen at safety and Olasunkanmi Adeniyi combined for about 30 or so snaps during their first season in the NFL. Allen missed most of the offseason, even going back to rookie minicamp, with injuries, and Adeniyi was on injured reserve for most of the regular season.
