Who to trade and for what position?

I have too many startable players and would like to package some of them for someone, however I cannot tell what position to package for. My team is:
QB: Mahomes
RB: Melvin Gordon, Leonard Fournette, Aaron Jones, Mark Ingram, Theo Riddick
WR: Davante Adams, Robert Woods, AJ Green, Sammy Watkins
TE: Eric Ebron, Jack Doyle
