The switch is for a noble cause: “Rockets guard Tracy McGrady will change his uniform number to No. 3 to promote his ’3 points Darfur’ initiative, with an announcement expected this week. McGrady put in the paperwork for the uniform change midway through last season and had received league approval. He was making the switch to his high school number to bring attention to his Darfur Dream Team campaign and 3 Points documentary, Newly acquired Trevor Ariza will wear No. 1 but could not show the uniform at the news conference last week while details of McGrady’s uniform change were completed.”
