Easy.
Rondo
Sefolosha (43% on 3s past two seasons)
Iguodala (38% on 3s past two seasons)
Smith (37% this season)
KG
A lineup that could actually happen, maybe with an another offensive shooter/defender off the bench like Lou Williams, Kawhi Leonard, or Wesley Mathews to finish games with.
You got your 2 fast break guys (probably the 2nd and 3rd most athletic guys in the league), 4 elite passers and 1 that's above average, floor spacers at every position, two pick and roll/pop threats, excellent rebounding, and the best defense in league (elite at every position).
I'd try to go at Afflalo or Ibaka if at all possible. Paul George would be ideal but I doubt Indiana ever lets go of him.
