To be clear, it’s the market, not the running backs, who are slow. At least hypothetically.
The Pittsburgh Steelers have over the course of the offseason taken the following actions in addressing their running back position, in order: 1) signed Fitzgerald Toussaint to an exclusive rights tender; 2) applied the franchise tag on Le’Veon Bell; 3) allowed DeAngelo Williams to hit free agency; 4) released Karlos Williams.
There are several first-year running backs on the roster during the offseason, of course, including a couple that spent some period of time on the practice squad last season, but nobody who is going to be likely to play a factor during the year for Pittsburgh, and so are not included here.
