Smart will get the start at point guard Friday versus Brooklyn. Since the Rajon Rondo trade, the Celtics have tried three different options at point guard in Smart, Evan Turner and Jameer Nelson. The rookie, who started Sunday's loss to the Heat, will notch his second start of the season, pushing Tuesday's starter, Nelson, to the bench. While Smart has struggled to score in his last three contests, he did post a 23-point, five-assist, four-rebound line earlier in the month, so he has some upside when given substantial minutes.
