ANALYSIS: NBA coaching staffs will still be required to dress in 'business attire', however they will no longer have to wear a sports coat. The league made it known that this does not mean coaches can start wearing track/sweatpants during games. Along with the changes to the dress code, the NBA also informed coaches that they must wear facemasks at all times during games.
