Follow the referee behind the ball, about 3-5 meters away from the ball. He can see all the players in the area as close as possible to the ball with his eyes (he needs to keep running and adjust his position), mainly responsible for the outside of the three-point line of 123 and 6. Main responsibilities: three-pointers and scoring or disturbing the ball, staring at the weak side (no ball position between 56- 12), rebounding foul (especially rebounding over the back), walking, 24-second violation, out of bounds (16 area left out of bounds, 3 right out of bounds), and also need to cooperate with the referee.
Lead the referee to swim between 456, and don't go too far beyond the three-point line on the left side, mainly responsible for the game under the basket. It can be said that the foul in area 45 should be punished by the referee. At the same time, when the ball is in the 123 area, the referee should also observe the whole game and punish the foul that the tracking referee did not see.
In short, the two referees mainly observe their own areas, and at the same time, they need to take into account what the other side can't see and cooperate with each other to make the right decision.
