Leveon for ODB (1 Viewer)

I have Leveon Bell, Lamar Miller and Melvin Gordon.1/2 ppr redraft league. we start 1 or 2 RBs and 3 or 4 WRs. My WRs are D Thomas, Snead, Jordan Matthews, Sharpe.

I can trade Bell for ODB, or I can trade Miller or Gordon for Allen Robinson. 

Which do I pull the trigger on or none?

I would prefer giving up Gordon for Robinson myself.

Bell and Miller are more proven and get a bazillion touches every game. I expect Robinson's productivity to return very soon.

gordon for robinson feels like a good sell high buy low
