Takeaways from this game:

-Atlanta racked up 32 assists in this game, but they still missed the defense and production from Zaza Pachulia, Ivan Johnson and DeShawn Stevenson. The bench supplied just 8 points compared to Boston's bench posting 46.

-Josh Smith's production was sensational all night, but he showed that it can all be for naught if you make a few key passing errors.

-Paul Pierce continues to be brilliant as the primary playmaker in Rajon Rondo's absence. He scored or assisted on all of Boston's points in overtime, and his 27 points and 7 assists were just enough to buoy the Celtics to victory.

-Courtney Lee and Avery Bradley continued their solid defense. Even though Atlanta moved the ball well and got some high-percentage looks, Lee and Bradley made some key stops throughout the night.

-Jason Terry was everything Boston hoped he could be tonight, piling up 19 points off the bench and playing some crucial minutes down the stretch.

-With the loss, Atlanta drops to a tie with Boston in the Eastern Conference standings. At 34-27, the two clubs trail the Chicago Bulls by a half-game.

Boston's bench outscored Atlanta's bench 46-8, and Doc appreciated it:

Doc on C's playing so many OTs: "The good part of it is we're winning. I'm proud of our guys. We competed all night. Our bench was great."

Atlanta had a depleted roster, and it was readily apparent throughout the evening.

J-Smoove paced the Hawks for much of the game, but he had a few costly turnovers at the end of regulation and in OT.

Outstanding playoff type hoops in Boston tonight, Josh Smith came up huge but also huge errors down the stretch that cost his team....

32, 9 and 8 is still awesome.

Final OT: Boston 107, Atlanta 102. Paul Pierce scored or assisted on every Celtics bucket in overtime.

A Pierce triple gets Boston back on the board. Good defense by Atlanta, but better shot-making by Pierce.

J-Smoove beats the shot-clock to put the Hawks back ahead.

His versatility comes in handy in almost every situation.

Avery Bradley had no help defense behind him, and Teague got an easy deuce.

Paul Pierce, true to form, carries Boston in OT (with a little help from Jeff Green and the backboard).

Celtics 99, Hawks 98, 2:33remaining in OT

Jeff Teague orchestrates things for the Hawks, and it leads to a mid-range bucket for Horford.

If Atlanta wins this one, it would be a nice steal for them, especially considering they're undermanned and on the road.

Hawks 96, Celtics 94, 4:02 remaining in OT

Josh Smith's buzzer-beater is errant, and the Celts and Hawks are heading to OT at the TD Garden!

A Garnett miss is rebounded by the Hawks with 2.2 seconds remaining.

An ill-advised behind-the-back pass from Josh Smith gives the ball back to the Celtics after the timeout.

Boston's turn to strike.

Whatcha got, Doc?

Josh Smith drew the attention of the defense, and he lobs it on a dime to Al Horford on the pick-and-roll.

Meanwhile, Boston is leaning on Pierce in the waning seconds.

Pierce out-finesses Al Horford for a step-back jumper.

His 20 points pace the Celtics, but Kyle Korver has tied this one up.

Judging by how they've defended the Celtics tonight, looks like Atlanta doesn't place any value on Jason Terry from point blank range.
