Corey Davis and James Conner FOR Diggs. Full PPR dynasty

I have the Conner and Corey Davis end.
I would love to take Diggs because I have Cousins, making a dynasty hookup for years to come. I already have OBj to pair him with. My other backs are Melvin gordon, Beast Mode, Gio B, Corey clement, Deonta Foreman. Help me out!
