What do Numbers Represent in Sports Team Uniforms?

Have you ever wondered what the numbers on the backs of custom team uniforms mean? Is it the lucky number of the player? Are digits assigned at random? Where did these figures come from? The number on a sports uniform is much more than just a number, as any player or sports fan knows. In many cases, the number becomes linked with specific players. Sometimes it is even retired with the player, as with Michael Jordan and his signature number 23. There is a lot of pressure when it comes to selecting a sports uniform number.
