Really need a WR2 - stacked at RB - who to let go/target?

[Sir Sydney 0]

12-team, PPR - 8-0, 2-game lead

So, I'm not desperate, but keenly aware of the knife-edge I've been balancing on.

My Roster:

• QB: Rodgers, Trubisky
• WR: Theilen,........Baldwin, Robinson, Cobb, DJ Moore
• RB: Barkley, Conner, McCaffrey, White, Thompson
• TE: Kittle, Doyle
• K: Lutz
• DST: Streaming (Dallas, Carolina)

So, if Theilen got hurt (bye week 10), I'm hurting big time. There are potential question marks with each of my stud RB1 RBs based on usage, or schedule going forward.

If I were to trade away one of these RBs, which would you choose, and what kind of WR combo could I get that could help me. Not many teams are active in this league, so my trade targets are somewhat limited. I don't think anyone wants Baldwin, Robinson, or Thompson.

Is Conner a sell high now? What if Bell sits out all year, on the condition that the Steelers don't tag him next year?
