There are all sorts of reasons as to why someone would own a basketball uniform. They could be a famous basketball player in the NBA. They could be a not so famous player on a home town school team. It is even possible to own a uniform of a famous player without being that person. In fact, many people do this to show off their love of a specific team or their admiration of a specific player. These fans buy replica uniforms to make themselves feel more attached to the team or player.
Small, home town teams deserve a basketball uniform just as much as any major NBA team would. This is why there are companies that specialize in these uniforms. This is so that coaches of these small teams can find a place to make uniforms that will fit their team. The basketball uniform is very important to the camaraderie of a team.
