If they fall to 9th they are in a one game do or die against a motivated opponent... do you think that they are going to love walking into that situation? Makes it more meaningless? For who?
For whom? For everyone!
North American sports already have this problem where you don't win anything in regular season. All it does is determine seeding. I guess if you're talking about baseball, only a few teams make the playoffs, but this new NBA format means that 2/3 of the league make the playoffs. With home court advantage becoming less important over the past couple of decades, and with the current lack(mostly) of fans, it's not that important which seed you get. I'd argue that we've learned the past few years that teams are more concerned about match-ups than home court advantage.
82 games is a lot to simply determine which part of the bracket a team ends up in. That's why regular season is getting more and more meaningless. That's why there's load management and why we're probably past the days of seeing teams win 60+ games. There's simply no benefit to going for it. Making it even easier to make the playoffs just adds to it.
Sure, it may be exciting to see middling teams duke it out to see who makes it past the qualification round of playoffs , but if you're concerned at all about what regular season has become, it's not good news. It's just going to make even more of those 82 games inconsequential.
