Trade Advice/Help

Ok which side do you want.

Gronk and Julio or Kamara and Graham

My current roster (weird rosters only 4 at each position)
RB: Gurley, Hyde, Kerryon, and Clement
WR: Julio, Edelman, A Rob and Kupp
TE: Gronk and Brate

Also 2-4 so maybe I’m tilting but I feel like I need a RB upgrade Badly.
