Nets-Celtics Trade

It has now been five years since this robbery trade which eventually "netted" the Celtics Jaylen Brown, Jayson Tatum, Kyrie Irving and let's not forget next year's Sacramento pick (as long as it's not first overall). 

Just thought this anniversary was worth remembering by Celtics fans. How is it possible that Danny Ainge has not won NBA Executive of the Year at any time during the past 5-years?
