Defensive Roles

Defensive Roles use matchup data to analyze the time each player spends guarding PGs, SGs, SFs, PFs, and Cs, along with each of our 12 Offensive Archetypes, to gauge what each player’s job is on defense.

Using this data, matchup data is integrated with some other data points, such as time defending the rim, to determine a role for each player: Point of Attack, Chaser, Helper, Wing Stopper, Perimeter Big, Mobile Big, or Anchor Big.

Just like Offensive Archetypes, a player’s Defensive Role can change in-season and from year to year based on how he’s used defensively in that particular season. Better fit of skill set to role may further optimize a player’s defensive performance and result in higher values in D-LEBRON and other defensive impact metrics.

A brief description of each Defensive Position:

  • Point of Attack: A guard who defends smaller ball handlers in pick-and-roll and in isolation on the perimeter with limited off-ball help responsibilities.
  • Chaser: A guard who sticks to shooters and cutters on the perimeter with limited off-ball help responsibilities.
  • Helper: A guard or wing helps away from his matchup, both on drives and at the rim.
  • Wing Stopper: A wing who defends Shot Creators often and is defending in pick-and-roll and in isolation on the perimeter, with some off-ball help responsibilities.
  • Perimeter Big: A big who does not defend in pick-and-roll as often and either stays with Stretch Big or Stationary Shooters on the perimeter or can rotate to help at the rim.
  • Mobile Big: A big who defends aggressively in pick-and-roll, often switching and hedging to push ball handlers away from the rim.
  • Anchor Big: A big who defends deep in pick-and-roll, often dropping to protect the rim.
