When the league expands to 32 teams, they should change the NBA Cup format to a 32-team single elimination bracket
Like how March Madness does their tournament
With 32 teams, you can do a single-elimination bracket from 32 down to 1.
32 -> 16 -> 8 -> 4 -> 2 -> 1
That way every team has a chance.
To seed all the teams from 1st to 32nd, just use their season record from opening day until December.
And have the NBA Cup championship game on Christmas.
