Kevin Garnett  must not like business trips to Atlanta all that much. The Celtics  center submitted a virtuoso performance that seemed fresh out of a 2008 time machine — including the go-ahead turnaround with 30 seconds left — carrying the Celtics to a 83-80 victory against the visiting Hawks and putting a bow on their Eastern Conference quarterfinals series in six games.
Garnett finished with 28 points, 14 rebounds and five blocks, becoming the first player in a Celtics uniform to register that kind of line in the playoffs since Kevin McHale  totaled 27 points, 15 boards and six blocks in 1986. Rajon Rondo  (14 points, 8 assists) and Paul Pierce  (18 points, 7 assists, 5 rebounds) were the only other C’s in double figures.
Trailing 79-78 with less than a minute remaining, Garnett dropped a turnaround in the lane that gave the Celtics the lead for good after they squandered a nine-point advantage in the fourth quarter. Following a stop on the other end, Ray Allen  made just 1-of-2 free throws with nine seconds on the clock, but Al Horford countered with 1-of-2 of his own with three seconds remaining. A pair of Pierce freebies put the finishing touches on the victory.
Thanks to a pair of missed Omer Asik free throws and two successful Andre Iguadola attempts at the charity stripe in the final seconds, the 76ers eked out a 79-78 victory against the Derrick Rose -less Bulls to win the series in six games. The win means the C’s host the Eastern Conference semifinals, including Game 1 Saturday.
WHAT WENT RIGHT
Ticket post: Garnett attempted just 12 field goals in Game 5, and half of them came from at least 18 feet. The Celtics made a concerted effort to get Garnett the ball in the post early, and he owned the paint from the start (on both ends). In Game 6, he took 10 shots — by halftime. All five of Garnett’s first-half field goals came within 12 feet of the basket, and he entered the break with 13 points, seven rebounds and three steals, as the C’s established a 47-41 lead through two quarters.
Backcourt boost: With little life in the building — and little for Celtics fans to cheer — four minutes into the second quarter, Rondo reentered the game for Keyon Dooling . The Hawks led 31-25. Over the next four minutes and change, the Celtics fired off a 16-0 run to establish a 41-31 advantage. Rondo had four points and three assists in that stretch and guarded 6-foot-9 Marvin Williams  on the other end (or the vicinity thereof, wreaking havoc as a roaming defender). Meanwhile, Avery Bradley  locked down a scoreless Jeff Teague  in the first half.
No sprain, no gain: When Pierce’s first 3-point attempt fell flat off the front of the rim, it had to be from the lack of lift as a result of his sprained MCL, right? Not so much. The captain made four of his next five field goals, totaling 12 points in 16 first-half minutes and erasing any concern over how his knee would respond.
WHAT WENT WRONG
Closing speed: After Garnett scored to give the Celtics a 74-65 lead with 8:41 remaining in the fourth quarter, the Celtics scored one field goal over the next six-plus minutes. They failed on four attempts to stretch the lead to double digits, and eventually the Hawks — led by four Horford buckets — stole a 79-76 lead with three minutes left.
Rondo from the get-go: Rondo finished the first quarter with only two points and two assists. His lone bucket came on the only time he got to the rim, and he even failed to get back for Kirk Heinrich‘s buzzer-beating jumper that gave the Hawks a 23-20 lead after the first quarter. The C’s offense runs on Rondo, and they followed his lead in the opening 12 minutes to the tune of 35.0 percent shooting for just seven field goals.
Putting a Dampier on things: Here was one particularly painful stretch in the early going: Rondo threw a pass meant for Mickael Pietrus  out of bounds, Horford missed a jumper, Erick Dampier grabbed an offensive rebound, Heinrich missed a 3-pointer, the Hawks grabbed another offensive board, Tracy McGrady  missed a jumper, Atlanta grabbed yet another offensive rebound and Marvin Williams buried a 3-pointer. Just an awful stretch in all aspects, particularly on the glass — against Erick Dampier.
