Dont want to keep distracting in the Cavs thread with this, but I think its really hard to say the game isnt healthier now than it has been for a few decades. Part of that is just how strong the talent pool is today compared to like 2002 (Nets back to back finals yikes). Another part is a series of rule changes that have toned down a lot of the negative or less interesting aspects of the game (excessive fighting, bad midrange heaves from journeymen). The game is not what it was in even the late 90s/early 00s. But it is a beautiful one and I love watching these modern speed ball offenses.
Do some teams push the three point hunting too far? Sure. I haven't been able to watch a Rockets game since they had Yao. Hardens offense is the least aesthetic thing on the planet. But we see a lot more good stuff based on motion, smart passing, and high IQ - the 14 Spurs, Heat this year, and yes, even the Warriors. I could write a few hundred words on these competing styles, but neither would really be possible without the rule changes that broke offenses open in the late 00s.
