I think the NBA definitely benefits from its jerseys, no way it succeeds in spite of them. I would never consider buying any jersey other than Celtics or suns if they were just normal jerseys, but I’d absolutely buy, for example, the heats miami vice jersey. Cool colors on uniforms definitely help sell merch and make people more excited about teams they otherwise wouldn’t care about at all. Of course, I say this based exclusively on personal experience and with no data
