My initial thought was the Thunder/Sonics, but I didn't look at enough for depth purposes, but a starting 5 of Payton, Westbrook or Allen, Durant, Kemp, and Sikma has to be up there. Did a quick look and I think they don't have enough overall depth on the bench (aside from Allen or Westbrook)?
Since I live in Cleveland, I will do the Cavs, even though I know they aren't the best, I have to give them some love.
PG - Mark Price, Kyrie Irving, Terrell Brandon
SG - World B. Free
SF - Lebron James
PF - Kevin Love, Larry Nance, Hot Rod Williams
C - Mark Daugherty, Zydrunas Illgauskas
So there is my 10, not the most balanced team because the SG's and SF's for the Cavs are terrible (outside of James), but I think that would be a fairly well crafted team with excellent shooters around James and solid interior defense from Daugherty and Big Z.
