Particularly in recent years, the Pittsburgh Steelers tend to try to draft juniors, whether redshirt juniors or true juniors, with a lot of their draft picks, especially the early ones. Often enough, players who come out early have the talent where, if they stayed in for their final season, they would raise their draft stock even higher, so it can represent good value in that sense.
Their 2020 NFL Draft class consisted of five of their six picks being seniors, including three redshirt seniors. The lone player remaining with college eligibility was fourth-round running back Anthony McFarland, who was a redshirt sophomore and had two years of eligibility remaining.
