NBA.com’s John Schuhmann gets you ready for the 2018-19 season with a key stat for each team in the league and shows you why it matters. Today, we look at the Detroit Pistons, who may have one more step to take defensively.
The Pistons are one of two teams that have improved defensively in each of the last four seasons.
In the 2013-14 season, the Pistons ranked 26th defensively, allowing 107.3 points per 100 possessions, 3.3 more than the league average. Then the Pistons hired Stan Van Gundy and, in regard to points allowed per 100 possessions vs. the league average, they improved in each of his four seasons as head coach.
The Utah Jazz are the only other team that has done the same, improving defensively (vs. the league average) in each of Quin Snyder’s four seasons on the bench.
Last season, the Pistons actually registered the league’s biggest drop in defensive rebounding percentage, grabbing 78.5 percent of available defensive boards (10th in the league), down from 81.2 percent (first) in 2016-17. But they saw big improvements in both opponent turnover rate (from 23rd to eighth) and opponent free throw rate (from ninth to third) to more than make up for the rebounding drop-off.
The Pistons moved up a few spots (from 19th to 16th) in opponent effective field goal percentage. And they did that despite seeing a big increase in the percentage of their opponent shots that came from the restricted area or 3-point range.
In each of the previous two seasons (2015-16 and ’16-17), Detroit was the best in the league at forcing their opponents to shoot from between the restricted area and 3-point range. League-wide over the last three seasons, restricted area shots (shot at 61 percent) have been worth 1.23 points per attempt, 3-pointers (36 percent) have been worth 1.07 points per attempt, and shots in between (40 percent) have been worth just 0.81 points per attempt. So if you’re forcing the shots in between, you have the structure of a good defense.
Last season, the Pistons took a step backward in that regard. In fact, no team saw a bigger increase in the percentage of their opponents’ shots that came from the restricted area or 3-point range. They went from 59 percent (lowest rate) in 2016-17 to 65 percent (14th lowest) last season. The much bigger jump came in the percentage of their opponents’ shots that came from beyond the arc, where they went from 31 percent (12th lowest rate) to 36 percent (fourth highest rate), which is interesting in regard to the Pistons’ new coach.
Last season, Dwane Casey’s Toronto Raptors saw the biggest drop in the percentage of their opponents’ shots that came from 3-point range. After allowing their opponents to take 33 percent of their shots (the league’s eighth highest rate) from beyond the arc in 2016-17, the Raptors allowed them to take only 29 percent of their shots (the league’s second lowest rate) from 3-point range last season. And that’s how Toronto saw defensive improvement (points allowed per 100 possessions vs. the league average) for the third straight season.
Forcing opponent shots from the least efficient areas of the floor isn’t everything in regard to defensive success. The Brooklyn Nets allowed the lowest percentage of opponent shots to come from the restricted area or 3-point range and ranked 25th defensively. And while Casey’s Toronto defense was terrific against the league’s not-so-great offenses, it had major issues against the top 10 teams on that end of the floor.
The Pistons just need to get better. And while there’s more room for improvement on offense, there’s still another step forward they can take defensively. In Casey’s first season in Toronto, the Raptors allowed 8.5 fewer points per 100 possessions than they did the season prior. That is the fifth biggest improvement in defensive efficiency of the last 40 years.
