Uniform numbers in American football are unusual compared to those in other sports. They are displayed in more locations on the uniform; they are universally worn on both the front and back of the jersey; and in many cases TV numbers are displayed on either the jersey sleeves, the shoulder pad, or occasionally on the helmets.
The NCAA, NBA [PDF], and WNBA [PDF] all enforce this general guideline. âOpposing team uniforms shall be of contrasting colors,â reads the official NCAA menâs basketball rule book. âThe home team shall wear light game jerseys and game shorts and the away team shall wear dark game jerseys and game shorts. This rule may be altered by mutual consent of the competing institutions.â How did this tradition start? Americaâs pastime probably had something to do with it.

Back in those days, teams sometimes had difficulty finding laundry services outside of their own cities.
