LET'S GET THE NBA FINALS STARTED! Thousands of people went to see the NBA Finals, with about 18,000 people (approximately the seating capacity of Madison Square Garden) inside the stadium and around 3,000 people outside watching the event. July 20, 2021, was a significant day for Milwaukee as the Bucks faced the Suns in a competition to win their first championship since 1971, which would also mark the Suns' first win.
