I'm surprised you don't have Embiid as an option for your poll as #1 pick.
If C's have the #5 pick and take Smart as BPA, I see Danny making a trade of either Smart or Rondo to pick up another asset in the draft or proven young player -- depending on how Rondo plays the rest of this season.
I see Smart as more of a PG than a SG so I'm not sure I would see them co-existing well on the court. I could be wrong on that but I think this would give Danny a great chance to move that pick for a pick a few slots down and a young player or future pick.
Any of the players you've slotted at 7-10 would fit a position of need better than Smart. Pick Smart for someone else while getting that extra asset.
As for the #20 pick, I don't know much about Payne other than some comments made on this site but I would think that Selden would be a better option as SG than another PF like Payne. Same for Hairston and GRIII. Even Isiah Austin at C would make more sense.
nice effort though. always good to see someone with the stones to put their thoughts out on their website
