Reduce costs. The Boston Celtics' stadium catering sponsor is TD Garden, and the cost of jersey distribution is borne by the team itself. In order to reduce costs, the Boston Celtics chose not to distribute jerseys. The Boston Celtics and TD Garden will also give out free T-shirts and other souvenirs on certain special game days or specific events, such as the playoffs. Therefore, it is a common practice for the Boston Celtics not to issue jerseys. This does not affect the influence and status of the Boston Celtics in the NBA and among fans.
