Kyrie Irving has been enjoying arguably his best season in the NBA, scoring, dishing and defending at a level we've never seen from him with this kind of consistency. But Irving will be the first to acknowledge that he's not perfect and will have nights when he doesn't shoot the ball as well as he would like. Thursday's game against the Los Angeles Lakers was indeed one of those games for Irving whose struggles in many ways mirrored the play of the Celtics as a team, losing 129-128 to the Lakers on a buzzer-beating jumper from ex-Celtic guard Rajon Rondo.
