How does Sankey compare to Emmitt?

Back when running backs carried more value in the NFL, a player like Washington's Bishop Sankey could have been a first-round pick. Now, with the position devalued in the eyes of most GMs, he likely will slide into Day 2. Still, there is plenty of upside to be culled from the running back position in the second and third rounds. Consider that Sankey has drawn comparisons to Hall of Famer Emitt Smith.
