Rajon Rondo leads the Celtics with 18 points, 10 assists and 10 rebounds in Game 7 against the 76ers to to an 85-75 victory and into an Eastern Conference finals matchup with the Miami Heat.
The Celtics will open the third round of the NBA playoffs in Miami on Monday night.
Bouncing back from his worst game of the playoffs and snapping out of a 32-minute slump in which he had just two assists and five points - Rondo scored nine straight Boston points after Paul Pierce fouled out to help the Celtics turn a three-point edge into a double-digit lead.
Rondo had 11 points in the fourth quarter, including his first 3-pointer in five games, made all four of his free throws down the stretch and grabbed his 10th rebound in the final minute - chucking it over his head and into the frontcourt to help the Celtics dribble down the clock.
Andre Iguodala scored 18 points, and Holiday and Elton Brand had 15 apiece for the 76ers, who eliminated the top-seeded Chicago Bulls in the first round but couldn't do the same with the Celtics.
Kevin Garnett had 18 points and 13 rebounds for Boston, and Ray Allen hit a pair of fourth-quarter 3-pointers after missing his first five attempts.
The Celtics will now face the actual NBA MVP LeBron James along with Dwyane Wade and the rest of the Heat. Miami advanced to the conference finals by eliminating the Indiana Pacers in six games.
Miami beat Boston in five games in the conference semifinals last year. In 2010, the Celtics eliminated the Heat in the first round and then knocked James and the Cavaliers out in the second - his final game with Cleveland before defecting to Miami.
This will be an interesting matchup!
