2020 NFL Draft class was special in a lot of ways. Only have six players selected, due to not having a first round pick after trading it for Minkah Fitzpatrick, not only did all six players make the team — they all played.
At this point, we all know how much the Steelers value their draft capital, which means they also value their draft picks. If the decision is between a drafted player and an Undrafted Rookie Free Agent (UDFA), they are likely to stick with the player they selected in the NFL Draft. Not that there aren’t exceptions, just look at last year when they parted ways with Quincy Roche for Jamir Jones.
