It was LaVine’s and Dunn’s first game back in Minnesota after the trade last June for Jimmy Butler. The Bulls were able to draft Markkanen with the selection acquired from Minnesota in the trade. The Bulls defeated Minnesota 114-113 in Chicago earlier this month in the return of Butler and Taj Gibson. The Timberwolves jumped out ahead in the sentimental return of former Timberwolves player Fred Hoiberg. LaVine, also. It was 17-6 Minnesota as the Bulls were quick to shoot with perhaps one pass per possession, again resulting in only tough shots for Markkanen and a scoreless first half. Markkanen did defend well against Karl-Anthony Towns, but the Bulls trailed 31-24 after one. Noah Vonleh did give the team a boost with a pair of threes and good defensive rebounding. The Timberwolves remained in control, taking a 42-33 lead four minutes into the second quarter before a switch to make LaVine also a facilitator turned the game around for the Bulls. LaVine drawing the defense had four assists in five possessions with three Nwaba scores on dunks and layups that gave the Bulls a 48-47 lead with 4:58 left in the half. Again, Minnesota’s defense was unable to show any resistance as LaVine drove for a three-point play and passing to Portis on the fast break for a lob dunk as the Bulls led 62-60 at halftime. LaVine had 15 points in the half and Portis 11. Andrew Wiggins had 17 for Minnesota as both teams shot 51 percent. Nwaba had 10 points and seven rebounds.

Jeff Teague continued to torment the Bulls in pick and roll and jumpers as the Bulls went under screens. Minnesota went ahead 74-71 with Towns finally getting going. But Portis powered inside for a score and 76-76 tie with 3:50 left in the third quarter. Back to back Bulls turnovers then enabled Minnesota to score five straight points and go into the fourth quarter leading 86-82. It was a poor start to the fourth quarter for the Bulls with the Bulls failing to get two loose balls on the defensive boards. Both led to Jamal Crawford threes and a 96-84 Minnesota lead with 9:24 left in the game. An 18-3 Minnesota start to the fourth quarter with three Crawford threes ended the Bulls hopes for a season sweep of the Timberwolves.
