I used to be against the Dec-Aug schedule when proposed in the past, but I came around to it since the pandemic. However, I don't think this is part of the plan any more, but they did consider it.
They are already talking about starting Dec. 1 with a condensed schedule, presumably to get back to the normal schedule for '21-'22. If they were open to a Dec-Aug schedule, they would likely plan to start later in December this year.
With the Olympics in July, it would probably not be the year to start a Dec-Aug schedule.
I mean that effects what, the players on 2 teams maybe 4 teams. How many of them are actually going to play in the Olympics anyway? I don't think that should be the driving force. I think a December to August season makes far more sense. Much less interference with football. Playoffs don't overlap with any other sports playoffs (so no overlap with hockey). Better weather and easier for fans to travel for playoffs with kids off school (also allows the younger fans to stay up later and actually watch more of the playoff games). It just makes a lot of sense to have the NBA Finals end right before football really starts and before baseball really gets it playoffs going.
46 NBA players on 23 teams played in the Olympics in 2016. Up from the record of 41 in 2012 (and if I had to guess, this is probably a record that has continually been broken every Olympics since '92).
Now of course all Olympians aren't created equal, and a lot of those guys contribute as much as Vincent Poirier contributes to the C's (Patricio Garino? Michael Gbinije? Nicolás Brussino?), but I've heard it's important to many of the international NBA players. Though I'm sure if the NBA changed it's schedule, most guys wouldn't play (so ya maybe only at best role players on 2-4 teams, if this went forward).
But the narrative that I've seen pushed for the last 18 years is that NBA players participating starting in '92 is what has fueled the growth of international players and fan bases. The NBA is still trying to grow internationally, I don't think they'd want to give up one of their best marketing tools for extending their reach. Maybe you could argue the decline of US supremacy in the international game combined with the best players often not playing greatly diminishes the impact of international competition, though I would disagree with that (one reason being foreign stars playing helps grow the game too).
Also an issue of summer ratings. There's a reason TV networks don't air new episodes of their hit shows in the summer, though you could argue a new, changing TV landscape here, which has some validity, but still don't think you'll ever continually draw biggest possible live broadcast ratings in July/Aug. Shorter, infrequent events (Olympics, World Cup) of which the NBA is neither, being the exception. Overall, I think warmer weather actually hurts the NBA (more people outside and traveling = fewer viewers).
Mapping out the proposed shift, I don't really see any benefit from a competition stand point. A few extra Sundays with no NFL competition, less NHL competition (but in my mind if you put fans/potential fans in a Venn diagram, NHL and NBA would have the least overlap), more MLB and special events (Olympics, World Cup, FIBA) competition. If anything, I think the league that benefits the most from this might be the NHL, not the NBA.
*Note World Cup is actually in Dec in 2022 for some reason, assuming this is a one off oddity.
The way I see it, the plus is more US kids able to stay up and watch the playoffs (which is really only a benefit for those in the East and Central time zones). The negative is less international exposure every couple of years? Nothing else really seems like much of a benefit to me. Definitely not enough to re-arrange a growing $8 billion business over. When NBA revenue starts a downward trend, then maybe discuss shaking things up.
Arena lease implications?
Those arenas are locked into their WNBA leases, so this whole proposal could never happen
