The new look Boston Celtics had made significant changes going into this season and it led them to another successful season near the top of the Eastern Conference. The Celtics let Kyrie Irving and Al Horford walk and replaced them with Kemba Walker and Enes Kanter. These moves paid off this year with Kemba being a much better fit on and off the court than Kyrie. You could argue that letting Horford go was questionable, but he has had a down year in a scaled back role in Philadelphia and the contract he earned (4 years $109 million) would have been too rich for Boston.
