As I often do in these challenges, I played Kyle Anderson in his real position (PG) and often posted up Steph. My silvers were Ariza Jabari (at PF) and Bogut. You need a defensive anchor in the middle who can defend on shaq and decent 3&D guys on the bench (also another bronze anchor, I used Kuzmic and he was really good). At the end I won at OT after having tied the game on the buzzer with jabari, second try.
P.S I know it's could be considered cheese, but playing a player in his real position (just watch a UCLA game of last year) is not IMHO, or at least it is borderline
For the bronzes I liked Ricky Ledo, Caboclo, Kuzmic, Cory Joseph and Inglis as a stretch 4, but You just have to try them!
Hope it was useful
