My preferred second unit was:
Delonte, Wafer, Marquis, BBD and Shaq/JO
not Nate, Delonte, Marquis, JO, SO
So we have Wafer and BBD. Bradley and Luke make for a very small second unit.
Nine player rotation:
Rondo, RA (SG/SF), PP (SF/PF), KG (PF/C), Perk
AB (PG w/ RA@SG), Wafer (SG/SF) BBD (PF or C w/ KG@PF) Luke(PF w/Perk or KG@C)
w/ Delonte is a lot easier:
Rondo, RA (SG/SF), PP (SF/PF), KG (PF/C), Perk
Delonte (PG/SG), Wafer (SG/SF), BBD (PF/C), Luke (PF w/Perk or KG @ C)
