RB start for this week

Need to pick one from the below for standard league semi final this week. Who would be your choice. Thanks

Mike Davis (Sea) Vs Rams
Kerwynn Williams (Ari) Vs @Redskins
Rod Smith (Dal) Vs @Oak

would pick williams as safest option and rod smith for higher upside.

Williams, Smith and then Davis. God Speed

Thanks. Morris in the side is holding me back on Smith. Williams is dependent on how well Gabbert plays and Davis is carrying injury. That’s the dilemma.
