What You'll Learn

Wilson basketballs were used by the NBA from 1946 to 1983
During this period, Wilson supplied the NBA with basketballs made from full-grain leather, which was easy for players to hold and created a great playing experience. Wilson's basketballs were well-liked by players and coaches, and the company's logo became synonymous with the NBA. However, in 1983, when Wilson's contract ended, Spalding replaced them as the sole ball creator for the league. Spalding's basketballs, made from full-grain leather, offered a superior feel and playing experience, becoming an instant hit.
In 2020, after nearly 40 years, Spalding decided not to renew its contract with the NBA. This decision presented an opportunity for other brands to bid for the coveted position of official basketball supplier to the league. Wilson emerged as the winner, reclaiming its former status as the NBA's official basketball manufacturer. The switch to Wilson basketballs coincided with the NBA's 75th anniversary season in 2021-22.
Wilson's return to the NBA was highly anticipated, with players like Trae Young expressing their excitement about using Wilson basketballs again. The company worked closely with the NBA and the National Basketball Players Association to develop and approve the new game ball through extensive testing and evaluation. Wilson's basketballs for the NBA feature the iconic logos of both the NBA and Wilson, embossed on the ball's full-grain pebbling.

Spalding basketballs replaced Wilson in 1983
Wilson, the original supplier of basketballs for the NBA since its founding in 1946, held the contract for the first 37 years. In 2020, however, Spalding decided not to renew its longstanding contract with the league, creating an opportunity for other brands to compete for the coveted position. Wilson emerged as the winner, reclaiming its title as the official basketball supplier.
The change from Spalding to Wilson in 2021 caused a stir among players, with some expressing displeasure at the switch. The new Wilson basketballs were shipped to hundreds of players before the season to get their feedback, but some still struggled to adjust to the different feel of the ball. Notable players, such as Paul George, commented on the lack of "touch and softness" compared to the Spalding ball.
Despite the initial mixed reactions, Wilson's return to the NBA after a 37-year hiatus is a significant moment in the league's history. The company's commitment to growing the sport globally aligns with the NBA's ambitions, and their high-performance game balls will be used across various leagues, including the WNBA, G-League, 2K League, and Basketball Africa League. Wilson's partnership with the NBA is expected to have substantial revenue implications, with the company believed to be paying between $25 million and $35 million annually.

Spalding's contract ended in 2021
Spalding's contract with the NBA ended in 2021 after nearly 40 years as the official basketball supplier to the league. The company first became the official ball of the NBA in 1983, taking over from Wilson, which had held the contract since the league's inaugural season in 1946.
In June 2021, Spalding announced the release of its final run of official NBA game balls, marking the end of a decades-long era. The decision to part ways was reportedly a mutual agreement between Spalding and the NBA. According to Spalding Vice President and General Manager Matt Murphy, the two parties worked on a new partnership agreement for several months in late 2019 and early 2020 but could not come to an agreement on the terms. As a result, it was mutually decided that the 2020-2021 season would be their last together.
The end of Spalding's contract paved the way for Wilson to reclaim its position as the official basketball supplier to the NBA. Wilson signed a new deal with the NBA and resumed its role as the official ball supplier starting with the 2021-22 season. This marked a return to the league for Wilson after a 37-year hiatus. The company had previously supplied basketballs to the NBA from 1946 until 1983.
The switch from Spalding to Wilson sparked some debate among players and fans. Some NBA players, such as Paul George and Nikola Jokic, expressed their preference for the feel and softness of the Spalding ball. They attributed their shooting struggles to the change in balls, claiming that it affected their shooting ability. However, others, like CJ McCollum and Malik Beasley, disagreed, stating that the responsibility for missed shots lies with the shooter rather than the ball. Despite the mixed reactions, the change to Wilson basketballs signalled a new chapter in the NBA's history, with the league embracing a different brand of basketballs after nearly four decades with Spalding.

Wilson became the official basketball supplier again in 2021
Wilson became the official basketball supplier for the NBA once again in 2021, replacing Spalding. This marked the end of Spalding's nearly 40-year run as the official basketball supplier, with Wilson reclaiming its position after a 37-year hiatus. Wilson supplied the NBA with basketballs from its founding in 1946 until 1983, when Spalding took over.
The switch back to Wilson was announced in June 2021, ahead of the 2021-22 NBA season, which was also the league's 75th anniversary season. The new Wilson basketballs were unveiled in partnership with the NBA, featuring the iconic NBA and Wilson logos in full-grain pebbling. The Wilson logo also included an anthracite inline. The basketballs were made from the same materials, with an eight-panel configuration and performance specifications as the league's previous game balls, and the same leather sourced from a Chicago tannery.
Wilson's return as the official basketball supplier was the result of a multiyear partnership with the NBA. As part of the deal, Wilson also became the official ball supplier for the WNBA, G-League, 2K League, and Basketball Africa League. The company's general manager of basketball, Kevin Murphy, emphasised the shared goal of increasing basketball participation worldwide, stating that "the commitment we and the NBA have to fuel growth in participation is at the core of this partnership."
The switch to Wilson basketballs received mixed reactions from players. Some players, like Portland Trail Blazers' CJ McCollum, suggested that players needed time to adjust to the new balls. Paul George, who is also the president of the NBPA, commented on the difference in "touch" and "softness" between the Spalding and Wilson balls. However, other players, like Minnesota Timberwolves' Malik Beasley, disagreed, attributing shooting inconsistencies to factors other than the ball itself.

Players have mixed reviews of the switch
The NBA switched from Spalding to Wilson basketballs at the start of the 2021-22 season, marking the end of Spalding's nearly 40-year run as the official ball supplier. Wilson, who had previously supplied the league from 1946 to 1983, reclaimed its position as the official basketball provider.
Players' Reviews of the Switch:
The switch to Wilson basketballs received mixed reviews from players in the NBA. Some players, like Portland Trail Blazers' CJ McCollum, suggested that athletes were still adjusting to the new ball and that it was different from the Spalding ball they were used to. McCollum, who is also the president of the NBPA, took responsibility for his missed shots, tweeting that it was "not the ball's fault." Minnesota Timberwolves' Malik Beasley agreed with this sentiment, stating that "it's not the ball" causing the slump.
On the other hand, some players expressed their dislike for the new ball. Paul George, for example, commented that the Wilson ball lacked the same "touch" and "softness" as the Spalding ball. He predicted that there would be a lot of bad misses and airballs due to the change. Nikola Jokic shared a similar sentiment, stating that he sometimes loses his grip on the Wilson ball during gameplay. These concerns about the ball's grip were echoed by other players, who noted that the change affected their shooting ability.
While there were no statistics to support the claims, field goal percentage across the NBA had decreased, and players attributed this decline to the new balls. However, it is important to note that other factors, such as adjustments to foul calls on 3-pointers, could also contribute to any changes in performance.
Despite the mixed reviews, Wilson's basketballs are widely used and well-regarded in high school and collegiate-level play. The Wilson Evolution, in particular, is known for its softness, tack, and superior grip, making it a popular choice among players.
