guys who are actually on the main roster first.

You could start with the below list, although I do think it's quite possible that Royce plays at the 4 and Exum at the 2. Even if both Exum and Mudiay played at the 2 the bench is still NWG until that changes. If the Jazz thought JWF would play they would have signed him to the main roster intead of (or in addition to) Oni.



Point guard:
Mike Conley Jr., Dante Exum, Emmanuel Mudiay, Nigel Williams-Goss

Shooting guard:
Donovan Mitchell, Royce O’Neale, Miye Oni

Small forward:
Bojan Bogdanovic, Joe Ingles, William Howard

Power Forward:
Jeff Green, Georges Niang

Center:
Rudy Gobert, Ed Davis, Tony Bradley
