Take care of the rock.
It’s the simplest of principles in basketball yet sometimes the most challenging.
No one knows this more than Rajon Rondo .
His 14 assists Wednesday gave him double-digit assist totals for 11 straight games, the first player with such a string since Steve Nash  went on his remarkable run in 2009. But in those 11 games, he’s committed six turnovers three times and four turnovers twice. Doc Rivers  challenged him after the All-Star break to cut down on the turnovers and see what happens.
‘Well it’s been down since All-Star break and we’ve had a couple of them, but overall our numbers are down and that’s huge,” Rivers said Wednesday. “We made some changes, which I probably should have made earlier in the year and since we’ve made those our turnovers have been way down.
‘The only big we throw it to is [Kevin Garnett ], above the elbow, basically its that simple,” Rivers added. “Before we were running all the elbow offense, but it was any big and we realized that maybe Kevin should be the only ball handler above the circle.’
And the change from Rondo?
“He’s probably talking about me,” Rondo said. “When I take care of the ball, we take care of the ball as a team so I try to go in with that focus. It starts with the point guard. I have the ball in my hands a lot of the time on the floor. So, if I can take care of the ball, we tend to follow.”
The turnover ratio can explain so much. It can explain why a team that has trouble taking care of the ball possession after possession allows its opponent to get easy buckets in transition.
In the college game, we’ve seen what the University of Kentucky has done turning teams over with its pressure defense. Close games become blowouts in the blink of an eye.
In the NBA this season, we’ve seen a Philadelphia team overachieve and lead its division for most of the season because they are hardly turning the ball over at all. They are on pace to commit fewer than 11 turnovers a game, breaking the previous record of the 2006 Detroit Pistons .
And now we’re seeing the benefit of taking care of the ball from Rondo and the Celtics .
The Celtics have been beaten on the glass by an average of 10 rebounds per game over a stretch in which they’ve gone 4-2. Why? Because they’re committing fewer and fewer turnovers. Take Wednesday night for example.
The rebounding tote board read 43-25 at one point in favor of Utah. But the Celtics committed just six turnovers three quarters while Utah had committed 13, leading to 18 Celtics points. The final numbers were 49-38 and 12-15, respectively.
