By rule, a defensive player must allow a moving player that is receiving a pass, outside of the lower defensive box, an opportunity to avoid contact. The speed of the player will determine the amount of distance an opponent must allow. On this play, Brunson does not give Gilgeous-Alexander an opportunity to avoid contact after receiving a pass outside of the LDB and therefore Brunson is not in a legal guarding position. The referees will then judge if the contact affects the SQBR (Speed, Quickness, Balance, or Rhythm) of Gilgeous-Alexander. If it does, this would be a blocking foul and if it does not then a no call would be appropriate.
