Why are there no jerseys 1, 2 and 3 in the international basketball game?

In the international basketball game (national team competition), we can see on the court that there are no athletes wearing the 1, 2, and 3 jerseys on the court. Why is there such a rule? It turns out that the FIBA ​​stipulates that the national basketball team's jersey number is from No. 4 to No. 15. The reason why there are no 1, 2, and 3 is related to the penalty in the game.

According to the rules of the FIBA, when the free throw is made, the referee raises his hand to extend 2 fingers, indicating 2 times; 1 finger is extended, indicating 1 penalty; the player has 3 seconds violation, the referee extends 3 fingers. .

When the player fouls or the team changes, the referee also gestures to indicate the player's number. If the players on the field set 1, 2, 3, it is easy to cause misunderstanding. Therefore, the basketball team does not have players 1, 2, and 3.

However, the NBA of the American Basketball Professional League is independent of the FIBA. The NBA's penalty is not affected by the jersey. Players choose it, so in the NBA, there will be 1, 2, and 3 jerseys, such as the All-Star Wade. In the No. 3 jersey, there will even be a No. 0 jersey. For example, Westbrook wears No. 0 jersey, but in general, the jersey number is below 55.
