The NBA schedule is sometimes a cruel beast. Take the Celtics  and Bulls, put them in a vacuum and the result is usually a fantastic game. But put them on a Saturday night with both teams on the second end of back-to-backs and you get a slow, ugly contest, like the one these two teams played.
The Celtics were able to hang in until the bitter end, mostly thanks to 21 Chicago turnovers, but the combination of Derrick Rose  (36 points) and Carlos Boozer (22) was too much to overcome in a 90-79 loss that snapped Boston’s four-game winning streak. (Recap .)
Credit Tom Thibodeau ‘s defense, which held the Celtics to 38 percent shooting and kept them out of the paint all night. Not many teams can make the Celtics look as bad as they did Saturday night, but Thibodeau knows them as well as anyone and he has Chicago ranked second (behind the Celtics) in defensive efficiency.
The Celtics return home for a six-game homestand against only two teams with winning records: Utah and Orlando. They are also expected to get Kevin Garnett  back, possibly as early as Monday.
WHAT WENT WRONG
Rebounding: In case there was still any confusion about how the Celtics feel about offensive rebounds, Doc Rivers  said it as plainly as he could Friday night.
“I don’t care about offensive rebounds,” the coach said. “I care about defensive rebounds.”
In that case, the first half was very discouraging as the Bulls grabbed eight offensive rebounds. It didn’t get any better in the second half as the Celtics got pounded on the boards. They gave up 11 offensive boards and lost the overall battle, 48-27.
Derrick Rose at the free throw line: Derrick Rose established a new career-high in free throw attempts and makes midway through the third quarter. He went on to make 15-of-19 as he wore the Celtics out with the pick-and-roll. The Bulls wound up only being +7 at the line, despite taking 13 more shots (35-22).
Bench production: Or the lack, thereof. Outside of Jermaine O’Neal  who had six points and three rebounds, the Celtics reserves combined to shoot 1-for-7 with three rebounds and four assists. Once again, the Celtics offense without Rajon Rondo  on the floor was disjointed and out of sync.
WHAT WENT RIGHT
Paul Pierce  and Ray Allen : The two veterans basically are the Celtics offense right now with Garnett out, so it’s a good thing that they are both playing at a high level. They combined for 40 points, or more than half the Celtics’ total. Along with Rondo, they shot 20-for-43. The rest of the team? A horrific 8-for-31.
Turnovers: Yes, this is the right column. The Bulls turned it over 21 times compared to the Celtics’ eight times. The Celtics recorded 12 steals, which helped, but this was the only thing that kept the Celtics in the game.
Rajon Rondo was decent: Rondo had a solid line with 13 points, five rebounds, five steals and eight assists, but he was also responsible (along with the big men) for Rose’s big night.
