In particular, the minor miracle series win vs Rockets and 25 point game 1 lead vs Warriors.
Instead of realizing that the game was passing them by and that they were mostly winning at that level because they lucked into an MVP caliber player, an All-Star (who wanted to play in San Antonio more than he wanted to be a Spur), continuity and defense, they ignored their structural issues, increasingly believed their own hype and doubled down on intangibles and tertiary things.
It culminated in their becoming so brazen that they actually had the audacity to think that this horrifically assembled roster could improve upon 47 wins, instead of realizing the error of their ways and why they were covered up.
The more enlightened, knowledgeable posters pointed out the festering issues during those seasons, but were scoffed at for supposedly being contrarians, pessimists, etc. In reality, we were seeing the forest from the trees.
Now, it's all come to a head and this franchise is increasingly becoming the laughingstock of the league.
