In the NBA, Ross, the top player, is the most typical No.1 player. The NBA is a basketball business alliance, so Ross is allowed to endorse the basketball bracelet 1.
Rules and special cases of the number of basketball jerseys: In basketball, there are no jerseys of 1-3 in some international competitions and some regular competitions, starting from the 4th, because there are three kinds of basketball achievements: 1, 2, 3. When the referee confirms the score, he will make a gesture (for example, he will stretch out his index finger when he gets 1), so the jerseys of players in international competitions are all issued by basketball associations of various countries, generally only 4- 15 jerseys. No.65438 +0-3 jersey is generally invisible in some domestic basketball games. The number 1-3 is typically the NBA, which is a basketball business alliance, so the number 1-3 is allowed. Generally, these jerseys are selected by the players themselves, not only with the number 1-3, but also with various numbers 1-2. At present, the largest number I have seen is the 9T of the rocket.
