broken up by referees and players alike. In the 2019 NBA off-season, the Nets signed point guard Kyrie Irving. Coming off two seasons with the Celtics, Irving was described as selfish by many critics. This impression caused many Celtics fans to blame him for the Celtics' inability to get through to the playoffs. During a regular season game in the 2019–20 season between the Celtics and Nets, the Celtics' fans displayed their displeasure with Irving by chanting "Kyrie sucks" in TD Garden. When the series returned to Brooklyn two days later, the Nets' fans chanted "Kyrie's better" in response to the chants in Boston. The "Kyrie's Better" chants reference to how the Celtics signed Kemba Walker after Irving left for the Nets. On May 30, 2021, a fan threw a water bottle at Irving at TD Garden following a Nets victory and a 3-1 lead in the series. New York Knicks The Knicks–Nets rivalry has historically been a geographical one, with the Knicks playing in Madison Square Garden in the New York City borough of Manhattan, while the Nets played in the suburban area of Long Island and in New Jersey, and since 2012 have been playing at Barclays Center in Brooklyn. Media outlets have noted the Knicks–Nets rivalry's similarity to those of other New York City teams, such as the Major League Baseball (MLB) Subway Series rivalry between the American League (AL)'s New York Yankees and the National League (NL)'s New York Mets, and the National Football League (NFL) rivalry between the National Football Conference (NFC)'s New York Giants and the American Football Conference (AFC)'s New York Jets, the result of the boroughs' proximity through the New York City subway. Historically, the boroughs of Manhattan and Brooklyn competed via the Dodgers–Giants rivalry, when the two teams were the Brooklyn Dodgers and the New York Giants. Like the Knicks and Nets, the Giants and Dodgers played in Manhattan and Brooklyn, respectively, and were fierce intraleague rivals. The rivalry between the New York Islanders and New York Rangers of the National Hockey League took on a similar dimension while the Islanders inhabited the Barclays Center, from 2015 to 2021. Due to the Knicks being located in Manhattan and the Nets being located in Brooklyn, some media outlets have dubbed this rivalry "Clash of the Boroughs".
