Shooting Efficiency and Turnovers (Chart)
We know a lot about shot creation. In a nutshell, the shot right at the rim leads in efficiency and brings plenty of free throws and offensive rebounds. The corner three is second in efficiency, followed by three point shots from other locations. The paint area, excluding the aforementioned area right at the basket, does not host high-efficiency shooting but causes plenty of defensive fouls. The mid range is low-efficiency shooting area and is bottom, too, in offensive rebound percentage.
The role of turnovers in shot creation was recently brought up by rodhig. He’s also had a Vassilis Spanoulis post that paints an accurate picture of Spanoulis’ shot creation in a four-game sample.
Field goal attempts from the 0-9 feet area (as ratio of total field goal attempts), according to the Hoopdata database, share a .391 correlation coefficient with turnover percentage in a six-and-a-half year NBA sample.
Likewise, an assisted corner three is unlikely to materialise without prior investment. At least two events need to happen: First, the defensive player needs to rotate off of the corner. Help is only applied when there is need for help, usually through a roll or a penetration. Second, a pass needs to be made.
These events carry the danger of turning the ball over, probably more so than a one-dribble pull up two pointer in isolation.
