Fantasy Upside
As SBNation pointed out, Kenneth Farrow, an undrafted free agent, saw his first meaningful NFL action last season in Week 2, getting four carries against the Jaguars after Danny Woodhead went down with a season-ending knee injury. Injuries opened the door for Farrow to make the team, they opened the door for him to get NFL carries, and they eventually opened the door for him to become the starter in Week 15 against the Raiders. Farrow was injured just a week later against the Browns and placed on IR.
Fantasy Downside
Farrow gained just 192 yards on 60 carries, good for 3.2 yards per carry. The offensive line play wasn't great, but Farrow did nothing to distinguish himself with his own effort.
2017 Bottom Line
With Branden Oliver back from the injury that sidelined him last year, Farrow falls down the pecking order behind Oliver and starter Melvin Gordon. Assuming he beats out Kenjon Barner and Andre Williams, Farrow's value is totally dependent on the health of the others on the roster.
