The Celtics  hadn’t won two games in a row since Dec. 13 and 16, gathering Ping Pong balls as they slid down the NBA standing over the past month, but the C’s improved to 2-0 with Rajon Rondo  and Avery Bradley  in the starting backcourt.
Rondo approached triple-double territory (8 points, 11 assists, 9 rebounds), Bradley contributed 14 points before tweaking his ankle again and the two combined for five steals in a 114-108 victory against the host 76ers.
Jeff Green  led all scorers with 36 points, helping the Celtics  (17-33) avenge last week’s buzzer-beating loss to Philadelphia (15-35) in the Garden. Jared Sullinger (19 points, 10 rebounds, third straight double-double), Brandon Bass  (18 points) and Jerryd Bayless (11 points) also reached double figures.
WHAT WENT RIGHT
Backcourt’s back: After missing two weeks with an ankle injury, Bradley picked up where he left off, scoring 17 points in his return on Sunday and reaching double figures against the Sixers within the game’s first 10 minutes. Despite playing four seasons together, Bradley and Rondo haven’t even started in the same backcourt for half a season’s worth of games. How that duo performs the rest of the way could dictate whether they remain teammates for years to come. The early returns are positive — on both sides of the ball, as Bradley and Rondo also helped keep Michael Carter-Williams (11 points) and Evan Turner  (12 points) in check.
Green thumbs up: Likewise, Green showed signs of the uber-athletic potential everyone imagined in his pairing with Rondo. Green had a baker’s dozen by halftime, and Rondo assisted on three of his five field goals — including back-to-back buckets during a 10-0 run that helped the Celtics  establish a nine-point lead just before halftime. Green’s confidence tends to build momentum when he’s involved early, and Rondo may help make that a trend.
Sharing the wealth: Actually, just about everybody benefited from Rondo’s presence. The C’s assisted on 13 of their 14 first-quarter field goals, taking a 34-23 lead after one, and finished the first half with 19 dimes on 23 FGs. Rondo had nine of the 19. While the Sixers made their runs to cut into the advantage — even taking the lead in the second quarter — the Celtics ‘ execution on the offensive end helped keep them at bay.
WHAT WENT WRONG
Awkward Klynyk: Kelly Olynyk continues to endure some growing pains. Brad Stevens  severely limited the rookie’s minutes during an all-around poor performance. In one tough-to-watch stretch, a Philadelphia shot clock violation bailed him out of biting on a Spencer Hawes  up-fake from beyond the arc, and then he committed a horrific turnover in transition. He finished with one point and two giveaways in 12 minutes.
Sloppy second: Stevens rested Rondo with a seven-point lead midway through the second quarter, and the 76ers immediately rattled off a 10-2 run that included a pair of Carter-Williams buckets in his absence. The stagnant C’s were forced to bring back the still recovering Rondo after just three minutes. Through three quarters, the Celtics  outscored the Sixers 68-57 with Rondo on the floor while Philly owned a 25-20 advantage with him on the bench.
Avery’s ankle: Bradley tweaked his ankle again late in the fourth quarter and sat the final 3:16. After his performance alongside Rondo the last two games, any more missed time would be another devastating blow.
