The Scoring Efficiency Matrix Explained
The scoring efficiency matrix plots every player on two axes: volume (PPG) and efficiency (TS%). This creates four quadrants that tell very different stories about a player's scoring value.
The gold standard is the upper-right quadrant: high volume and high efficiency. These are the players who score a lot AND do it efficiently. They represent the most valuable offensive players in the league because they don't need excessive possessions to produce elite scoring numbers.
The Four Quadrants
High Vol / High Eff: The elite scorers. They carry heavy offensive loads while maintaining top-tier efficiency. These players are typically MVP candidates.
High Vol / Low Eff: Volume scorers who sacrifice efficiency. They score a lot but require many possessions to do it. Their value depends on whether the team has better options.
Low Vol / High Eff: Efficient role players. They don't score in huge quantities but make the most of their opportunities. Often the ideal complementary pieces for championship teams.
Low Vol / Low Eff: Players who neither score much nor do it efficiently. These players typically provide value in other areas like defense or playmaking.
Frequently Asked Questions
What is a scoring efficiency matrix?
A scoring efficiency matrix plots players on two dimensions: scoring volume (PPG) and scoring efficiency (TS%). This creates four quadrants that categorize players by their scoring profile.
Which quadrant is the most valuable?
High Volume / High Efficiency is the most valuable quadrant. These players produce elite scoring numbers while maintaining top efficiency, making them the most impactful offensive players.
Can a player move between quadrants?
Yes. Players can shift quadrants based on role changes, team context, and development. A young player might start as Low Vol / High Eff and grow into High Vol / High Eff as they become the primary option.
Why use TS% instead of FG% for efficiency?
TS% accounts for three-pointers and free throws, giving a more complete picture of scoring efficiency. FG% treats all shots equally, but a three-pointer is worth 50% more than a two-pointer.
How are the quadrant boundaries determined?
The boundaries are set at the league average for both PPG and TS%. Players above average in both dimensions fall into the elite quadrant; below average in both fall into the bottom quadrant.
