I think you still have to go Jones Jr here.
Fitz actually has some pretty awful home/away splits. Even though it’s a heavy passing game script, not sure i trust that offense yet as Fitz/DJ are only weapons. And if Cardinals learned anything from Oakland, RSJ should be the main beneficiary.
I wouldn’t hate it if you went Kupp though. Going to get matched up vs some of the worst slot CBs in the league. If you need the upside, play jones. If you need the floor, play Kupp. If you’re referring to yahoo projections, they’re a joke so wouldn’t pay too much attention to him. Just look at your opponents roster and see how risky it is and counter it.
