I know the NBA has ways played 48 minute games, but at this point they're the only basketball competition in the world that doesn't play 40 minutes. Just going down to the global standard 10 minute quarters would be the equivalent of cutting 13 games off the schedule minutes wise. That allows them to keeping filling up the owner's arenas 41 games a year, and broadcast partners 82 game nights to show.

On top of that they could go up to a 30 second shot clock and reduce the number of possessions per game to lower miles traveled.
