Trade Value for Juju/Lockett

My Team is
QB: Philip Rivers/Josh Allen
RB:CMC, AP, David Montgomery, Damien WIlliams and Devonta Freeman
WR: Juju, Lockett, RIdley, Josh Gordon and Jarvis Landry
TE: Mandrews

I was interested in trying to make a move to improve my RB core and was curious what you think I could get for something like Juju or Lockett and a RB not named CMC.
Or maybe im over thinking im currently 1-1-1 any insight would be awesome

I’m in a very similar situation with Juju and Lockett and I’m trying to trade for a RB. I don’t want to trade Lockett…I think he’s a stud for where he was drafted. I am thinking about offering up Juju for Marlon Mack straight up in my league. Tough situation though…
