After witnessing the Spurs score nine points in the third quarter, including an abysmal 4-of-18 shooting, I couldn’t really stomach too much more.

I couldn’t blame you if you turned off the television.

But, in the grand scheme of things, the Spurs needed a win like this one. While the Spurs couldn’t muster anything of significance on the offensive side of the ball, they excelled, unusually, defensively.

Their 28-point second half, somehow, was good enough to pull away from a Celtics team that also couldn’t find the rim. After Paul Pierce clanked a fadeaway jumper over Tim Duncan, the Spurs had completed an impressive second half of defense — or possibly this just stemmed from the Celtics slightly more palatable offensive inefficiency. Boston finished the second half with 38 points off 14-of-36 shooting (38.9 percent), losing out on a good chance of increasing their win streak against the second-ranked offense in the NBA that, uncharacteristically, looked vaguely similar to that of the Toronto Raptors.

For once, it was the Celtics who totaled more assists and less turnovers than the Spurs. This was the fourth time all season that that has happened.

But, the Celtics left a lot of points on the board considering they missed seven free throws and, subsequently, gave up eight more offensive rebounds.

For an offense that chucked 28 3-pointers to no avail — actually, the Spurs did shoot 53.4 percent on 2-pointers — and stifled themselves with their lack of ball movement, those opportunities alleviated the qualms of inefficiency.

Tim Duncan, Manu Ginobili and Tony Parker combined for 25 points on 11-of-32 shooting and we still won. Six Spurs attempted a 3-pointer, but only three actually converted one. And we still won. In 17:36, Kawhi Leonard totaled zero points on 0-for-2 shooting, two assists and one rebound. And, again, we still won.

As a Spurs fan, I feel pretty good about the fact that in almost every facet of basketball, the Celtics had us beat. Not too mention that the Celtics were playing pretty good basketball prior to this game. The Avery Bradley, Rajon Rondo combination that I was focusing on played well. They combined for 36 points, 11 assists, five steals, four rebounds on 17-for-31 shooting.

Bradley, particularly, wasn’t afraid of guarding Manu 40-feet from the rim — which, usually, isn’t a good thing but Bradley is just that good of a defender — and his offense actually hurt the Spurs. I didn’t count specifically but he is adept at cutting off the ball right before Rondo gets into the teeth of the defense. If you are caught ball watching, Bradley takes advantage. And, given his defensive prowess, that’s all you really need to be successful in basketball.

Now that the Oklahoma City Thunder have dropped another game, the Spurs are tied in the loss column and only one game back of the No. 1 seed. Ugly wins like this one don’t count against us in the standings and, for that, I’m grateful.

Next time, we should try scoring the basketball with some regularity. That would be nice.

– Celtics injury report: Jermaine O’Neal (left wrist) is out. Ray Allen (sore right ankle) and Mickael Pietrus (head injury) are questionable.

– Celtics enter game off a 91-72 home-court victory over Miami Heat. Rajon Rondo posted his fifth triple-double of the season (16 points, 14 assists, 11 rebounds).

– In the month of March, Rondo averaged 9.6 points, 4.4 rebounds, 12.9 assists, 2.1 steals off 40.3 percent shooting.

– The Celtics are 6-2 in their last eight games against the Spurs. Their two losses, however, have came at the TD Garden.

– Keep tabs on Rondo’s assist tally. The Celtics are 20-8 when he notches at least 10 assists but a measly 4-10 when Rondo gets less than 10 assists.

– 6’2″ rookie point guard Avery Bradley has been playing really well as of late. Doc Rivers has increased his minutes because of his superior defensive acumen and his ability to mesh well with Rondo. In 97.3 minutes, the Rondo-Bradley-Pierce-Bass-KG lineup has allowed 87.6 points per 100 possessions and a 34.7 shooting percentage.

– Bradley is averaging 39.4 minutes, 14.6 points, three rebounds, 0.8 assists and a 52.8 shooting percentage in his last five games — which, coincidentally, coincides with their winning streak.

– The Celtics are on a five-game win streak that has put them atop Atlantic Division and into No. 4 playoff spot in Eastern Conference.

– Boston has allowed an unreal 87.1 points per 100 possessions in their last five games.

– Boston excels at preventing 3-pointers, allowing 16.3 3-point attempts per game (league average is 18.3). Teams have only mustered a 30.1 3-point percentage, good for first in the NBA.

– Boston is No. 1 in assist percentage. 66.9 percent of their shots are assisted.

– The Spurs like to bait teams into taking a bevy of long 2-pointers and that skill could be valuable tonight. Boston attempts 23.3 from 16-23 feet.
