The Bulls are the worst shooting 3 point team in the league by
percentage and only 4 teams take fewer 3s per game than the Bulls. No
team takes as many 16-23 foot jumps as the Bulls. In fact, the next
closest team, Minnesota, shoots 3 (!) less per game than the Bulls.
This is even more outrageous when you consider that the Bulls are in
the bottom 8 in the league in pace (averaging 2.5 fewer possessions per
game than league average), so that a huge percentage of their shots per
game are 16-23 foot jump shots. Even more discouraging is that the
Bulls don't even shoot that shot better than average. The average rate
of makes in that range is 38.5% leaguewide, but the Bulls make them at
a rate of just 37.1%.
The Bulls also take the 5th fewest shots
at the rim and are the 3rd worst team at finishing at the rim. They are
13th in shots taken in the under 10 foot range, but they are making 50%
of these shots, good for the 4th highest percentage. They are also 13th
in attempts in the 10-15 foot range, but they are 9th in FG% on shots
in that range.
There's a link describing where the data comes from inside the article as far as more thoughts on the topic.
However, that sums it up really. The Bulls offense is bad because they take a ton of long two point jumpers. It's statistically speaking, the worst shot in basketball. It has the highest degree of difficulty relative to the pay off, and the Bulls are killing the league in attempts at it while also being below average in effectiveness with it.
I doubt the Bulls offense is designed with the hopes of taking tons of long twos, but when you don't have three point shooters, a low post option, and limited slashing ability that's what you're going to get.
This is really a statistical representation backing up several of my observations with the roster spacing and team construction from earlier.
