xA (expected assists)

If a player who takes a shot receives a pass within 5 seconds before taking the shot, the player who makes the pass is assigned an xA value equal to the xG for the shot (indicating that the likelihood of the shot becoming a goal is the same as the likelihood of the pass becoming an assist). The xA for a player in a game is calculated as the sum of xA values for that player. This parameter is generated automatically.
