When fantasy managers are looking to fill their flex spots, it is often a tough decision. The flex rankings try to mix the value of running backs and wide receivers (and tight ends). A player like Robby Anderson, for example, may not make the WR3 cut, but on a team that is stacked with wide receivers, he may be the best flex option, as he is close to WR3 territory because of the great matchup this week.
A running back that is in the same position is Devin Singletary. It's hard to justify starting him as one of the two best running backs on your team (depending on your team), but he's the perfect guy for a flex spot. In two games he has 154 rushing yards and a touchdown. He does lose goal-line work to Zack Moss (at least he did in Week 2 when Moss was active), but Singletary certainly can provide value to fantasy managers.
