Rajon Rondo  scored just nine points, but he was the best player on the floor all night, taking over the fourth quarter in a 101-96 victory against the two-time defending NBA champion Heat. Of course, it didn’t hurt that LeBron James  (back spasms) was relegated to the Miami bench, but still — this was Rondo’s night.
The Celtics  point guard finished one point shy of a triple-double (15 assists, 10 rebounds), ending a five-game losing streak. Avery Bradley ‘s 23 points, including a career-high six 3-pointers, led the scoring effort, and four other Celtics  reached double figures: Brandon Bass  (18 points), Jared Sullinger (14 points), Jeff Green  (13 points) and Kelly Olynyk (10 points). And the Celtics  needed all of it from each of them.
The Celtics  improved to 23-46, moving one win ahead of the Lakers and Suns for the NBA’s seventh-worst record.
WHAT WENT RIGHT
Bradley’s back: After making just six of his 25 attempts from outside of 10 feet in his first three games back from an ankle injury, Bradley found the stroke that made him so successful early this season. The soon-to-be free agent knocked down three of his six first-half 3-point attempts and added a long jumper to enter the break with 11 points. In all, the C’s shot 50 percent (9-18) from distance over the first two quarters and stayed within 56-53 after two.
Charmed third: Working inside and out, Bradley and Brandon Bass  shot a combined 8-of-8 from the field to score 21 of the C’s 27 third-quarter points. Rondo was on the feeding end of four of those buckets, finishing with six assists in the frame. As a result, the Celtics  took an 80-78 lead heading into the fourth quarter.
Bench press: The C’s bench situation isn’t pretty. It’s comprised of four guys who weren’t on the team to start the season, two rookies and another player with 45 NBA games under his belt entering the year. Yet, they received valuable contributions from three of those seven players, as Sullinger, Olynyk and Jerryd Bayless (7 points, 5 assists) combined for 28 points, 10 rebounds and seven assists.
WHAT WENT WRONG
Worst first: The opening quarter couldn’t have gone much worse for the Celtics  defense. While the NBA’s two-time defending MVP sat on the bench, the Heat still scored 34 points on 70 percent shooting to take a 12-point lead in the game’s initial 12 minutes. It wasn’t Dwyane Wade  or Chris Bosh who victimized the C’s, but Udonis Haslem . The Miami veteran scored 12 points on 6-of-7 shooting in the first quarter.
No LeBron: The Heat announced James would miss his first game in a month shortly before tipoff. It remains to be seen whether he’ll return Friday in Miami, but regardless of how they feel about him, Boston fans missed a player worth the price of admission. Perhaps a motivated Celtics  team took it as a sign of disrespect, too.
