The Efficiency Landscape
Mapping teams by adjusted offense and adjusted defense simultaneously
The Efficiency Landscape maps every Division I team on a scatter plot with Adjusted Offensive Efficiency on the vertical axis and Adjusted Defensive Efficiency on the horizontal axis. Three diagonal tier lines divide the chart into zones based on each team's net efficiency margin relative to the season's top team. The result is a visual where both overall strength and stylistic profile are immediately visible — which teams are balanced, which are offense-first, which are defense-first.
What It Measures
The landscape plots each team's offensive and defensive efficiency on the same chart, making it possible to see both how good a team is and how they achieve that quality. Net efficiency (AdjEM = AdjO − AdjD) is captured by the diagonal tier lines — teams above a given tier line have a stronger net rating than teams below it. Two teams with identical AdjEM can have very different profiles: one through elite offense and average defense, the other through the opposite.
Why It Matters
AdjEM summarizes overall quality but erases the distinction between offense-driven and defense-driven teams. That distinction matters for matchup analysis, tournament projections, and stylistic understanding. The Efficiency Landscape makes the composition visible — a scout, analyst, or fan can see at a glance where a team sits on both dimensions and how unusual or typical their profile is compared to the rest of Division I.
How to Interpret
The vertical axis (Y) is Adjusted Offensive Efficiency — higher is better. The horizontal axis (X) is Adjusted Defensive Efficiency, oriented so that lower (better) defensive ratings appear toward the right side of the chart. Teams that combine elite offense and elite defense cluster in the upper-right corner of the plot, which is the championship-caliber zone. Three diagonal tier lines divide the chart based on net efficiency margins relative to the season's best team. Title Favorites are above the top tier line. Final Four Potential teams fall between the top and second lines. Hit or Miss teams fall between the second and third lines. The Rest fall below the third line. Clicking any team logo navigates to their full team profile.
Technical Notes
- Tier lines are diagonal because they represent constant Adjusted Efficiency Margin values — AdjO minus AdjD equals a fixed number. Teams anywhere along a given diagonal line have the same net rating, regardless of how they divide that margin between offense and defense.
- Tier thresholds are computed relative to the season's top team's AdjEM, not as fixed absolute values. This means the tier lines shift position each season as the national top-end changes, keeping the tiers calibrated to the actual competitive landscape each year.
- The national baseline (the top team's AdjEM used to anchor tier lines) is computed from all Division I teams before any conference or tournament filter is applied. Applying a conference or region filter changes which teams are displayed but does not move the tier lines — they remain a stable national reference.
- The defensive axis is reversed relative to its numerical direction: as you move right on the chart, adjusted defensive efficiency numbers decrease (i.e., fewer points allowed per 100 possessions). This orientation places elite defenders on the right side, consistent with the standard convention that rightward or upward always means better on both axes.
- Average lines for both AdjO and AdjD are overlaid on the chart, representing the national Division I mean for that season.
- •The landscape is a snapshot, not a projection. Teams can shift significantly as the season progresses and adjusted ratings stabilize.
- •Being in the Title Favorites zone does not guarantee a title — it means the team's efficiency profile is among the strongest relative to the current national field.
- •Early-season placements carry more uncertainty because adjusted ratings are less stable before 15+ games are played.
- •The landscape captures two efficiency dimensions but does not directly reflect Four Factor style, resume strength, or tournament matchup dynamics.
- •Teams with unusual stylistic profiles (extreme tempo, heavy zone, high foul-rate play) may sit in atypical chart positions relative to their win-loss record.
Illustrative: Team A has AdjO 120.0 and AdjD 94.0, placing them in the upper-right corner above the Title Favorites tier line. Team B has AdjO 115.0 and AdjD 94.0 — same defense, less offense — placing them slightly lower on the chart, in the Final Four Potential zone. Team C has AdjO 120.0 and AdjD 101.0 — same offense as Team A but weaker defense — placing them to the left and below. All three are strong teams, but the landscape makes their stylistic and quality differences immediately readable.
