Who gets the start among these options.?

Turner and Gore are the right RB choices. I'd monitor that shoulder situation with Big Ben closely, conflicting reports are usually not a good sign. I know Helbeck doesn't have anybody to throw to but they are playing possibly the worst p defense in the league at home. If there's any doubt as to Ben's situation I'd switch to Matt. While he went off last week, Moss is the easy bench at WR, A Johnson is an absolute beast and Moss's numbers last week are much more likely to be an anomaly than Boldin's were. Best of luck!
