Embiid and Saric. I think that will allow us to tank again next year while Embiid develops and Saric plays out a year in Europe before we buy out his contract. Even if Embiid becomes a HOF level player, I don't see him doing much next year. In 2016 most of our bad contracts will be up and we'll have Embiid + Saric + KO + Sully + Lottery pick in 2015 + Clips pick, then at the end of that season we'll have our pick and most likely a Nets lottery pick, plus tons of cap room.
I would also love Gary Harris if he fell to 18th - currently DraftExpress has him at 15th, but I think even that is very optimistic. I trust Danny to sort through James Young, TJ Warren, KAnderson, Jerami Grant, Rodney Hood, etc. Wiggins and Harris would be incredible, though.
