OBJ/Cooper trade and ROS?

I am looking to improve my WR core in a full ppr league. Any thoughts on OBJ/Cooper going forward?

my team:
QB: Lamar Jackson
RBS: Lev Bell, Gurley, Chris Carson, David Montegomry, Singletary, Malcom Brown
WRs: Thielen, Robert Woods, DJax, John Brown, sutton
TE: herdon, Mark Andrews

OBJ’s owner team

QB: Watson, winston
RBs: Ekeler, Barber, Kerryon(IR now)
WRs: OBJ, Cooper, Juju, AJ green, Fuller, Slayton
TE: mcdonal, everett

bump up for advice

Rather have Cooper by far this year.

carson for cooper? or do you think gurley + john brown for copper?
