Tracy McGrady wore No.3 jersey in high school, but has been wearing 1 since he entered the NBA. An important reason for McGrady's switch to the No.3 position this time is to promote his "three-point aid plan", which aims to help the poor in Africa and build schools for the children there. McGrady visited Africa in 2007, and then he filmed a documentary called "Three Points", calling on the world to pay attention to the lives of local victims. He donated $75,000 to the local humanitarian foundation. ? The number 3 jersey is the number of many super guards. Iverson, Wade, Butler, Marbury and Big Ben all wore the No.3 jersey. Of course, McGrady may not worship one of the superstars, but just want to start over in the number of superstars. Yao Ming is injured and will miss next season, so as long as McGrady is not traded, he is undoubtedly the boss of the team. At the beginning of next season, we will see the same familiar figure, except that his jersey number is changed to No.3?
