I have been thinking about the same thing.
Figuring a roster of
PG IT, Smart
SG Hayward, Brown
SF George, Tatum, Ojeleye, Nader
PF Horford
C Zizic
that leaves 5 roster spots and likely signing the other 2nd round picks (Brid and Allen) to 2 way d league contracts.
Players I would target
1. Try to resign Jerebko
2. Resign D Jackson
3. Sign two vet bigs out of this list Amir, Bogut, Sully, Humphries, Bass, Lavoy Allen,Mcroberts, Ezeli (if healthy)
4. Find a true 3rd PG maybe Mo Williams, Calderon, or Phil Pressey
possible lineup
PG IT, Smart, Calderon, Jackson
SG Hayward, Brown
SF George, Tatum, Ojeleye, Nader
PF Horford, Jerebko, Bass
C Amir, Zizic
