The magic number, on the eve of the regular season is 439.
As in: There are 439 players on NBA rosters heading into Opening Night after Monday's final wave of cuts.
Only nine of the league's 30 teams, in fact, have elected not to carry the maximum 15 contracts ... in many cases for luxury-tax reasons. They are:
Boston Celtics (14)
Chicago Bulls (13)
Indiana Pacers (14)
Los Angeles Clippers (14)
Memphis Grizzlies (13)
