Why worry about duplication when you are a borderline Lottery team?
We need talented players. If we happen to draft a PG and he happens to be better than Stuckey or Bynum then we make a trade.
Same thing if we draft a SG.
We need TALENT - you don't pass on the best guy available because yu have somequality player already. You take the best guy and hope they can play together or make a trade
