Blockbuster Trade Idea

Trying to trade up for a top 5 receiver. Willing to offer A wr2 such as Brandin Cooks and a rb1 such as Melvin Gordon to acquire one. Who should I go after? Right now I’m leaning towards OBJ or AJ Green. I’m in an 8 team standard scoring league and my roster is

QB; Rodgers
RBs; Shady, Freeman, Gordon, Martin, Carson, Kelly, Cohen
WRs: Michael Thomas, Demaryius Thomas, Brandin Cooks, Adam Thielen
