Last season, the Pittsburgh Steelers had a late bye week, and they used that opportunity to get a good look at some of their bottom of the roster guys. In the wake of that time period, running back Isaiah Pead was released and Fitzgerald Toussaint was promoted to the 53-man roster.
In a short amount of time later, Toussaint passed Jordan Todman on the depth chart and ended up starting two playoff games. He remains on the roster to this day as the third running back, although he has hardly played at all this season.
