The NBA is unlike many other sports leagues in that there is plenty to follow even after the NBA Finals ends. The NBA Draft and free agency take place not long after the end of the season, but one of the biggest gatherings of NBA personnel now takes place at the Las Vegas Summer League.
While there are also leagues in Orlando and Utah, it is the Vegas league that sees the biggest turnout. It has gained a lot of popularity over the past few years as it gives fans a first look at top draftees every year.
