2nd Running Back?

[Random Reason]

Hey fellas, new to the forum, new to FF (1st timer).

Anyway, we use 2 running backs, 1 point / 10 yds. I'm starting Mojo, but I'm not sure who esle to start? I have:

Thomas Jones
T.J. Duckett
Tim Hightower
LenDale White

I know Jones seems like the obvious 2nd starter, but Seattle is playing St. Louis and Duckett scored on them both times last season. But, Jones may still get more points than Duckett. Or.... what about Hightower. AZ is playing SF, and he should get the majority of the carries right? I'm assuming they don't just pass all day.

So who to start for my 2nd running back?

Great, I just read Mojo left the game last night with a bruised leg. I guess this is a welcome to FF.
