If the Pittsburgh Steelers roster had one single glaring omission from it, positionally, following Saturday’s initial 53-man roster assembly, it would obviously have been the stark lack of a second true running back on the roster, which is why Mike Tomlin fielded questions directly about this position afterwards.
Tomlin acknowledged that he would be watching the waiver wire at the running back position, but hastened to add that it was true of all positions. Indeed, any good organization will habitually watch the waiver wire daily as a due diligence exercise, because there is no bad time to strengthen your roster.
