What to do? Free Agent Question

[BloodSugar8]

So in my league we start 1 RB. I have Michael Turner and Kevin Smith. Turner has a Bye tomorrow and Smith is a Game Time Decision. I have to either start a questionable Smith or Drop him for a Free agent. Some of the RB's Available include Joseph Addai, Reggie Bush, Marshawn Lynch Jonathon Stewert and Darren Mcfadden. Should i drop Smith for one of these Rb's or hold onto him for the long run?

I do like McFadden alot this week, BUT there is no way I would drop Smith. Can u drop someone else from another position.

[BloodSugar8]

No, if i drop someone i must pickup someone of the same position
