After the 3 signings:
pg: Smart, Thomas, Rozier
sg: Bradley, Young, Hunter
sf: Crowder, Turner, Wallace
pf: Johnson, Sully, Jerebko
c: Zeller, KO, Mickey
Except for Wallace and Young or Hunter all of those 2nd and 3rd string guys can get minutes. That means no one can really get above 30 minutes. If they do, someone will not be happy.
Even if you sit Mickey all year, sharing 96 minutes with 5 (maybe 6) guys just won't work at the 4-5. To a lesser extent the 1-2 with 5-6 guys filling those minutes.
1. Move Bradley to give Smart, Thomas, Rozier, Young/Hunter minutes.
2. Move KO/Sully to give Zeller, Johnson, Jerebko, Mickey, (KO/Sully) minutes.
I saw a suggestion of trading Wallace, Hunter, and a 1st or 2nd for Hibbert. Would still need more moves but I wouldn't mind Hibbert for that trade.
