Offense and defense leaders
Total impact alone can hide shape. These leaders show who is driving value on offense, on defense, and on both sides at once.
Best offense
Julian Champagnie
Total+0.058
O+0.052D+0.029
Creates the strongest positive impact with the ball.
Best defense
Shai Gilgeous-Alexander
Total+0.054
O+0.035D+0.043
Creates the strongest positive impact on defensive possessions.
Best two-way
Shai Gilgeous-Alexander
Total+0.054
O+0.035D+0.043
Maintains positive value on both sides instead of leaning one-way.
How to use this
Start with the total score, then check the split. That tells you whether a player is winning with offensive creation, defensive resistance, or a stable two-way mix.
This is usually more actionable than a homepage-wide distribution chart because it helps you compare archetypes immediately.
The deeper player and team pages already carry these splits. The homepage should expose them too.
