Couple things:
Haven’t seen it mentioned here, but the final 4 teams have IST patches on their jerseys similar to the Finals patches.
A thought: Although the league didn’t explicitly say it, was the reason they didn’t want teams wearing uniforms too similar to the color of the floor was to avoid having problems with the digital court ads on the TV broadcast? That was why the Bucks’ cream uniforms got nixed a few years ago, right?
