Even more impressively was that Deng got his 40 points on an efficient 14-19 from the field, 3-5 from three-point land, and 9-11 on free-throws.
Deng was aggressive all night, giving the Bulls a second scorer they will need until star acquisition Carlos Boozer comes back from his fractured pinkie finger.
Held to an 11 point per game average throughout the first two games, Deng started off the game very hot, scoring 16 points in the first quarter.
The Bulls also got a double-double from both Derrick Rose and Joakim Noah.
Rose had 16 points, 13 assists, and five rebounds, however, Rose also had a game-high six turnovers. On a few occasions, Rose tried to force the issue and got himself into trouble with double teams, but overall, Rose was fantastic.
Rose found the open man, as evident by his 13 assists, and attacked on the fast break when the chance was there.
"I thought Derrick [Rose] was fantastic today," coach Tom Thibodeau said.
Noah had himself a solid double-double- with 10 points, 10 rebounds, four assists, and a block- but foul trouble plagued him most of the second half.
Noah had some great passes, ran the floor very well, and slowly but surely, is making the $60 million deal look like a bargain for the Bulls.
Another bright spot was Kyle Korver's energy and shooting off the bench- scoring 11 points, along with 4 assists.
After a breakout preseason, Bulls fans expected a big season from the former Utah Jazz, however, he has struggled to shoot thus far this season, and didn't come into tonight's game until around the 10 minute mark of the second quarter.
Korver's main responsibility will be to space the floor for a Bulls team that was putrid from three-point land last season. Although Korver only hit one three-pointer tonight on two attempts, he'll get several looks this season, and will have to hit them for the Bulls to be feared from downtown.
Young center Omer Asik had the best game of his young career, with 6 points on 2-3 shooting, 7 rebounds, and 3 blocks.
However, Asik fouled out in 26 minutes, and went 2-6 from the free-throw line. Asik has struggled from the charity stripe this season, showing an area the coaching staff must work on him with.
Former Bulls fourth overall pick LaMarcus Aldridge had a team-high 33 points and 9 rebounds, however, the Bulls held star guard Brandon Roy in check, as he scored just 17 points on 4-12 shooting.
For one night, Deng took advantage of a hot start and kept the aggressive pace up throughout the whole game.
Bulls fans hope this aggressive attitude keeps up until Boozer gets back.
