6. Golden State Warriors (Average Attendance: 19,596)
When you have one of the greatest teams in the history of sports, you are going to have a strong fan base. How much of that fan base is just bandwagoners is a subject for another day, but there are few teams more popular than the Golden State Warriors.
A big part of the fanfare attached to the Warriors is superstar Steph Curry. Curry just might be the most popular player in the entire NBA, especially by kids.
