The looking into trading up and trading down is part of DA's job. He has to look into every possible situation. I don't see s senario where trading up happens unless Orlando really likes Smart and knows he will be there at #6. (#6+KO+future 2nds for #4 and draft Exum).
I think Love is plan A,
If plan A fails I wouldn't be shocked to see the Kings trade up to #6 to draft smart. Leaving the Cs at #8 to draft Gordon or Saric and add some type of future asset.
