Off-Ball Player Data: Advantage Creation 1v1
The advantage_creation_1v1_off_ball_player section in the markings response contains one row per off ball player (both offense and defense) for 1v1 advantage-creation plays (i.e. isolations and post ups), with off-ball matchup and positioning context.
Overview
This data set provides off-ball player context around 1v1 actions, including:
- Player and matchup identity
- Start-of-play positioning and regions
- Distance metrics to ball, hoop, and matchup throughout the play
- Weak-side vs. strong-side positioning flags

Start-Frame Positioning
player_start_x
Type: float | Unit: inches
Off ball player's x coordinate at play start
player_start_y
Type: float | Unit: inches
Off ball player's y coordinate at play start

Type: string
Off ball player's start region. null if the player's start location is unavailable.
matchup_start_x
Type: float | Unit: inches
Matchup player's x coordinate at play start
matchup_start_y
Type: float | Unit: inches
Matchup player's y coordinate at play start
matchup_start_region
Type: string

Start-Frame Distances / Ranks
play_start_hoop_distance
Type: float | Unit: feet
Off ball player's distance from rim center at play start
matchup_play_start_hoop_distance
Type: float | Unit: feet
Matchup player's distance from rim center at play start
play_start_ball_distance
Type: float | Unit: feet
Off ball player's distance from the ball at play start
matchup_play_start_ball_distance
Type: float | Unit: feet
Matchup player's distance from the ball at play start
play_start_matchup_distance
Type: float | Unit: feet
Off ball player's distance from matchup at play start
play_start_speed
Type: float | Unit: feet/sec | Nullable
Off ball player's speed at play start. null when coordinates are unavailable.
play_start_matchup_speed
Type: float | Unit: feet/sec | Nullable
Matchup player's speed at play start. null when coordinates are unavailable.
play_start_lowness_rank_left
Type: integer | Nullable
Lowness rank among players on the left side at play start (1 is lowest on that side). null if player is not on the left side. "Lowest" means closest to the basket.
play_start_lowness_rank_right
Type: integer | Nullable
Lowness rank among players on the right side at play start (1 is lowest on that side). null if player is not on the right side. "Lowest" means closest to the basket.
play_start_lowness_rank
Type: integer | Nullable
Lowness rank at play start in one number. This shows the left-side rank when it exists, otherwise the right-side rank, so it matches whichever half of the floor the player is counted on with the same interpretation as those fields (1 is lowest on that side; lowest means closest to the basket). null when both side-specific ranks are null (player is not placed on either side for this snapshot).

These fields represent the off ball player's positioning and movement at the moment the 1v1 ballhandler releases a pass (if they passed during the 1v1).

Type: float | Nullable
Distance to matchup at ballhandler pass start (feet). null if no pass exists.
pass_start_ball_distance
Type: float | Unit: feet | Nullable
Distance from the player to the ball at pass start. null when no pass occurred or coordinates are unavailable.
pass_start_player_region
Type: string | Nullable
Player region at ballhandler pass start. null if no pass exists.
