Wilson also will supply balls for the WNBA, NBA G League, NBA 2K League and Basketball Africa League. The NBA and Wilson haven’t disclosed the terms of the deal other than to say it’s multiyear, but it’s believed to be 10 years. The NBA’s relationship with Wilson isn’t a new one. The company provided NBA game balls from 1946, when the NBA launched as the Basketball Association of America, until Spalding took over the contract in 1983. “We didn’t spend a lot of time having to get to know them or know what they’ve done throughout the course of this history and brand,” LaRocca said.
