The Nets superstar struggled in the first three games of the Eastern Conference first-round series. Smith said:"Kevin Durant is one of the greatest players in NBA history, and I consider him to be the best player in the world today regardless of what just happened in this series. And I think exhaustion played a part, and I think we are going to learn he was a bit injured as well."As great as he is as a player, he is that poor as a leader. You’re the face of this, and you’ve been deferential, because you're deferring to your boy Kyrie. He's going to give you what he's got. The problem is that he clearly lets others off the hook."KD and the Nets were swept by the Celtics in the franchise as Durant shot less than 38% from the field in this series and less than 34% from beyond the arc.Is Stephen A.
