Probably be Bradley and Kuzma
Cousins & Kuzma for Bogdan works. I feel like they would prefer to keep Bradley for his contributions this season vs. Cousins who is rehabbing his ACL (Not to mention they already have 3 other guys who have been great contributors at C this year: Davis, McGee, & Howard)
They'd probably still prefer to start Bradley & Green at PG & SG (defense focused with LeBron & Davis on the floor to handle offense), and then use Bogdan as their 6th man off the bench. Bogdan running the PnR with Davis, McGee, & Howard would make his life much easier than here in SAC.
I would prefer to move Bogdan for someone younger (Kuzma is 24) and who at least has 1 more year on his rookie scale deal.
