Putman, Carl (September 11, 2017). "Basketball Official Size & Weight". LiveStrong.com . Retrieved 2018-02-02. The duties [3] of the basketball referee are exactly this: to ensure the game is played safely and fairly. The referee enforces the rules of the game and in a game will make hundreds of decisions—determining when a violation or foul occurs and then stopping the game to issue the correct penalty.

Further complicating the job of an official is the proximity to the crowds. Unlike football or baseball, the crowd is nearly always located within a few feet of the official, as are coaches and other players on the bench. To combat this, officials are able to remove a fan from the arena with an ejection.

Positions and responsibilities [ edit ] A diagram of the relative positions of basketball officials in "three-person" mechanics. The lead official (L) is normally along the baseline of the court. The trail official (T) takes up a position approximately level with the top of the three-point line. The center official (C) stands across the court near the free-throw line. The partnership will tip off at different times by league. The NBA Wilson game ball will first be used during the league's 75th anniversary season in 2021-22. The other debuts will be during the 2022 WNBA season, 2021-22 NBA G League season, 2021 NBA 2K League season and the inaugural BAL season.Our commitment to growing the game of basketball on the global stage is at the heart of Wilson and our new partnership with the NBA," said Kevin Murphy, General Manager, Wilson Basketball. "Our passion for this game and the league runs incredibly deep, as does our history with it. And as we start this new chapter in the game, our focus and energy will be on supporting the league and the players, coaches and fans with the most advanced, high-performance game basketballs possible. Nike had the contract to produce balls for the Euroleague Basketball (operators of the EuroLeague and the EuroCup) from 2007 [9] until 2012, when it turned to Spalding. In the Philippines the NCAA (unrelated to the American NCAA) and UAAP use the Nike 4005 Official Tournament Balls.

Regardless, both classes of officials have equal rights to control almost all aspects of the game. In most cases, the lead official (in FIBA, the crew chief) performs the jump ball to begin the contest, though NFHS, NCAA, and the NBA, have allowed the referee to designate which official (referee or umpire; in the NBA: crew chief, referee, or umpire) shall perform the jump ball. Spalding was the first company to produce a basketball for official use. Company founder A. G. Spalding made the first dedicated basketball in the last years of the 19th century at the behest of James Naismith. It has produced basketballs since that time and was the NBA’s official game ball supplier from 1983 to 2021. They also produce the basketballs for the WNBA and NBA G League. The company also produces a wide variety of balls for the consumer market. The officials must ensure that the game runs smoothly, and this encompasses a variety of different responsibilities, from calling the game to player and spectator management. They also carry a duty of care to the players they officiate and to ensure that the court and all equipment used is in a safe and usable condition. Should there be an issue that inhibits the safe playing of the game, then it is the job of the officials to rectify the problem. Quite often, the job of an official surpasses that of the game at hand, as they must overcome unforeseen situations that may or may not have an influence on the game. Our partnership with Wilson fittingly comes to life as we approach our 75th anniversary season,” said Salvatore LaRocca, NBA President, Global Partnerships. “As the NBA’s official game ball for the league’s first 37 seasons, Wilson makes its return building on our shared history and looking ahead toward the continued growth of the league.”

On Wednesday, the NBA announced yet another change, but a subtler one. Starting in the 2021-22 season, Wilson will take over as the league's official ball manufacturer. Spalding currently holds the distinction. Fortunately for players and purists, the new ball will be made with the exact specifications of the current one, as the league revealed in its press release.

In 2012, it also became official provider for both the EuroLeague and EuroCup competitions. [6] It also serves as provider for Liga ACB. Players and team executives polled throughout the preseason have generally described Wilson’s balls, once broken in, as performing no different than Spalding’s model.

Note that the ball used for all competitions (men's, women's, and mixed) in the formalized halfcourt game of 3x3 combines characteristics of the size 6 and size 7 balls. Its circumference is that of a size 6 ball, but its weight is that of a size 7. [5] History [ edit ] A historic basketball. NEW YORK – The NBA today released the complete game schedule and broadcast schedules for TNT, ESPN, ABC, NBA TV and ESPN Radio for its landmark 75th Anniversary Season.A basketball is a spherical ball used in basketball games. Basketballs usually range in size from very small promotional items that are only a few inches (some centimeters) in diameter to extra large balls nearly 2 feet (60cm) in diameter used in training exercises. For example, a youth basketball could be 27 inches (69cm) in circumference, while a National Collegiate Athletic Association (NCAA) men's ball would be a maximum of 30 inches (76cm) and an NCAA women's ball would be a maximum of 29 inches (74cm). The standard for a basketball in the National Basketball Association (NBA) is 29.5 inches (75cm) in circumference and for the Women's National Basketball Association (WNBA), a maximum circumference of 29 inches (74cm). High school and junior leagues normally use NCAA, NBA or WNBA sized balls. [1] [2] On Friday, Jan. 7, the Los Angeles Lakers will host the Atlanta Hawks on ESPN (10 p.m. ET).
