From my understanding:
1) only 2014 is protected. And that is because ATL can swap with BK (only if they do worse that BK), and if they do not the pick is ours. Obv perfect scenario would be for celtics to have first overall pick then Atl and BK having the 3rd overall pick (this is what a lot of my friends are fantasizing about lol).
2) 2016 & 2018 = unprotected
3)We have the right to swap our picks with BK in 2015 & 2017(first rounders)
I was fielding questions from my buddies and thought I would ask here....thanks in advance guys
