This might seem like cheating, but given how horrendous the Detroit Lions have been thus far I think it's important to call out this backfield in particular. Other than Ameer Abdullah's big Week One outing, no Detroit running back has shown enough production to warrant starting with confidence. I suppose Abdullah is still the back you'd want to own, and the only guy you can even consider starting at this point. But between his fumble issues and the fact that this is going to be a four-headed monster upon Joique Bell's return, this is a situation to avoid.
Zach Zenner received the majority of the carries against Arizona last week, while Theo Riddick ended up reeling in the most receptions. Still, the Lions haven't really committed to one guy and no one has broken away from the pack. With Joique Bell's return imminent, this is going to get worse before it gets better. Honestly, if you need the roster space, you can probably drop any of these guys for an upgrade on the waiver wire. Let someone else deal with this mess until the Lions establish some semblance of a ground game.
