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 Minnesota Timberwolves, who couldn't slow down the opposition.
According to Second Spectrum tracking, the Wolves allowed their opponents to take 20 percent of their shots in the first six seconds of the shot clock.
That was the league's highest rate.
For every team in the league, effective field goal percentage is highest in the first six seconds of the shot clock. Last season, league-wide effective field goal percentage was 59 percent in the first six seconds of the shot clock, 52 percent with 6-18 seconds on the clock, and just 43 percent in the last six seconds of the clock, according to Second Spectrum.
So good defense starts with good transition defense. And as was the case with the Wolves, bad defense starts with bad transition defense. The 20.1 points per game the Wolves allowed in transition were second most in the league, according to Synergy tracking, and the 110.1 points per 100 possessions they allowed overall had them in the bottom six defensively for the fourth straight season.
The Wolves were better than average in regard to forcing turnovers (they ranked fourth at 15.5 opponent turnovers per 100 possessions) and keeping their opponents off the line (they ranked 11th in opponent free throw rate). But they ranked 25th in defensive rebounding percentage and, most importantly, ranked 27th in opponent effective field goal percentage.
Their defense wasn't good inside or out, but was worst at protecting the rim. The Wolves were one of just three teams - Cleveland and Orlando were the others - that ranked in the bottom 10 in both opponent field goal percentage in the restricted area (66.8 percent - 29th) and the percentage of their opponents shots that came from the restricted area (33 percent - 23rd).
Better transition defense, of course, would lead to fewer layups and dunks for the Wolves' opponents. But you have to wonder if the Wolves can get better defensively if they're forced to trade Jimmy Butler.
The Wolves allowed 12.9 fast break points per 48 minutes. That number was lowest (11.0 per 48) with Tyus Jones on the floor. But Butler's presence seemed to have a positive impact as well, with Minnesota opponents averaging 12.0 fast break points per 48 minutes with Butler on the floor and 13.9 per 48 with him off the floor.
Overall, the Wolves allowed 6.8 fewer points per 100 possessions with Butler on the floor (105.6) than they did with him off the floor (112.4). They saw a similar boost on offense (where they scored 6.4 more points per 100 possessions) with him on the floor.
Those numbers require some context. The Wolves' bench was bad, with huge drop-offs when Butler was replaced by Jamal Crawford and when Karl-Anthony Towns was replaced by Gorgui Dieng. Still, if the Wolves lose Butler, they're losing their best two-way player.
Either way, if they're going to get better defensively, improvement has to start in transition.

WOLVES NOTES - GENERAL
