PHILADELPHIA — It was his biggest miss as a Celtic and Courtney Lee knew it. This wasn’t a regular miss in a regular loss. Lee missed everything and it exemplified his struggles in Boston.

With the Celtics ahead by a point in the final minute of overtime, Rajon Rondo found an open Lee in the corner, his favorite spot on the floor. Lee gathered the pass and fired a 23-footer that never had a chance, the ball soaring 3 feet over the basket for an embarrassing airball.
