The deal
Sixers get: 2017 No. 1 pick
Celtics get: 2017 No. 3 pick and 2018 L.A. Lakers first-round pick if No. 2-5 (otherwise the Sacramento Kings' 2019 first-round pick or the Sixers' 2019 first-round pick, whichever is more favorable, unless it is the No. 1 pick, in which case Boston gets the less favorable pick)
