Current roster with past histories. 5 former #1 picks.

I am always curious as to which former team and or teams Steeler free agent acquisitions used to play for and how high they were drafted. Surprised to see 5 former #1 draft picks in Justin Fields, Cordarrelle Patterson, Mike Williams, Minkah Fitzpatrick, and Patrick Queen. If not drafted by the Steelers, I listed which team or teams they were previously on from most recent left to right (with years with that team) and how they were obtained by their original team on the far right. (for example, D2-18 means second round draft pick in 2018, or FA not drafted, free agent)
