In 2015, we had Darren McFadden, who was coming off three seasons with the Raiders where he had averaged 3.4 or less per carry. He also had a bit of an injury history. Backing him up was Joseph Randle and Lance Dunbar and competing for a roster spot were Gus Johnson and Lache Seastrunk. Like this year, we chose not to take a running back in that year's draft, but it was considered a stronger RB draft.
To his credit, McFadden actually outperformed expectations, averaging 4.6 per carry in 2015. Hopefully, Elliott will have that kind of revival. Randle was essentially Dowdle and Dunbar maybe Vaughn (although Dunbar was better than Vaughn at this point but worse than Freeman).
