Nets 109, Celtics 107: Jack of all trades

BOSTON -- Jarrett Jack, one of the players acquired by the Brooklyn Nets as part of a three-team swap that included the Boston Celtics in July, hit a pull-up free-throw line jumper over a chasing Marcus Smart with 27.5 seconds to play as the Nets rallied for a 109-107 triumph on Friday afternoon at TD Garden.

The Celtics led by 11 with under nine minutes to play, but the Nets rallied to tie the game with 4:15 to go. Brooklyn didn't get its first lead of the second half until Jack's jumper.

The Celtics acquired Marcus Thornton, Tyler Zeller, and a Cleveland Cavaliers' future first-round pick as part of a three-team swap that landed Jack in Brooklyn in July. Primarily a bench weapon during his career, Jack started and thrived on Friday. He added some late free throws to cap his game-high 27 points.

Jeff Green and Jared Sullinger -- two players that spent noteworthy time on the bench in the second half of Tuesday's loss in Orlando -- responded with solid efforts to lead the Celtics. Green scored a team-high 22 points on 10-of-18 shooting, while Sullinger added 19 points with eight rebounds.

Sullinger nearly forced overtime when he hauled in a full-court inbounds feed from Gerald Wallace with 1.5 seconds to go, but his turnaround baseline jumper rimmed out.

Smart's start: Celtics rookie point guard Marcus Smart is struggling with his shot, he's still learning how to be a distributor at the NBA level, but his defense and grit have already made him an impact player. Midway through the third quarter, Smart went hard to the floor to corral a loose ball and had the presence of mind to quickly advance the ball to a streaking Jeff Green for an easy bucket that helped Boston open a double-digit lead in the third quarter.

Green Day: Green, who was not on the floor late in the fourth quarter when the Celtics nearly rallied out of a monster hole on Tuesday in Orlando, scored 12 first-quarter points on Friday. His most noteworthy bucket was this nifty reverse alley-oop off a feed from Avery Bradley.

Loose balls: The Celtics initially ran with a nine-man rotation, but Brandon Bass made a fourth-quarter appearance. Gerald Wallace came in late for the full-court heave to Sullinger. Phil Pressey was a healthy DNP. ... The Celtic shot 51.7 percent from the floor; the Nets finished at 49.4 percent.

What it means: The Celtics fall to 10-17 overall, while the Nets move to 13-15. One day after playing old friend Kevin Garnett, it's off to Washington for the Celtics who meet old friend Paul Pierce in the tail end of this back-to-back on Saturday night.
