From an ESPN article on 10 story lines to follow during the slow period.
10. Unemployed NBA Players
There won't exactly be bread lines, but some players you watched play in the NBA last season will be looking for work somewhere else soon.
To save money, many teams (even the wealthy Lakers) have decided to carry short rosters -- just 13 players, instead of the allowed 15. On opening night, there could be 30 or 40 fewer NBA jobs than a year ago. At the same time, dozens of draftees and imported free agents (everyone from David Andersen with the Rockets to new Bull Jannero Pargo) have already filled roster spots.
As of this morning there are 381 signed players. If every team sticks to a roster of 13, just 24 more will get contracts. (As many as 71 could get jobs -- that would put every roster at the maximum 15). Meanwhile Chad Ford lists 40 notable free agents, from David Lee to Morris Almond. The full list is at 70.
Do the math. Forced retirement is a quiet reality of every summer. This year, the musical chairs could be especially harsh.
-----------------------------------------------------------------------------------------------------------
My bet is that most teams will stick with 13-14 players. There is a problem in the bolded section with his math. 30 teams @ 13 players is 390 roster spots. That would leave only 9 openings. To get to the 24 number it would have to be 13.5 players per team (15 teams @ 13 players; 15 @ 14). If all 30 teams carry full 15 man rosters that is 450 roster spots...less the 381 signed and that leaves a max of 93.
