The Chicago Bulls will have a lot to work on with their offense this season. Derrick Rose is hurt, on the off-chance you've been living under a rock, and they'll have to fight a lot of close, gritty games this season. But as noted by CSN Chicago, the Bulls' defense looked vastly improved in the preseason, and that could be a big factor in them winning games this season.
With a 97-90 win over the Indiana Pacers on Friday, the Bulls finished their preseason schedule with their fourth-straight win and third-straight game holding the opponent to 90 points or less. They were second in the NBA in defense last year, and this preseason, they showed no signs of slowing down.
As noted by CSN Chicago, there's plenty of stats to back that up. They allowed 87.1 point in six games, with the Milwaukee Bucks being the outlier, as they managed 94 points, but it was in a losing effort. Their opponents made less-than 41 percent of their field goal attempts in seven games, the fourth-best mark in the league.
In short, this defense looks to lead the team to wins while Rose recovers from his injury. The preseason has been a pretty clear indication that they have not regressed.
