The NFL Draft is less than a month away. Our SCB Steelers Draft Previews are rolling along. Check out our breakdowns of the Quarterback and Wide Receiver groups. Today, we stay with the offensive skill positions and look at the running backs. This year’s running back class is deep but there is no top-end talent and it is almost certain that none of them will be taken in the first round. After using a first round pick on Najee Harris last year, they don’t need a top-end starting back. What they do need is someone who can play on third downs and potentially be a serviceable backup if Harris goes down for a game.
