Anyone who says "whiny " as much as you do is a whiny .
The Spurs FO was able to build in place for the better part of two decades, because they had a base of Tim, Tony, and Manu. They couldn't accept the fact that they didn't have the talent to put with Kawhi, and they didn't have trade pieces. They should have taken one year to rebuild two seasons ago. They let their collective ego tell them that they didn't have to do that. Losing Kawhi just sped up the decline. Mortgaging the future on Patti and Pau was unforgivably bad.
It doesn't matter what they did in the Tim Duncan era, they have been inept since. The goal is not to get into the playoffs, it is to get back to having a legit championship contender.
Getting late round bargains isn't enough to build a championship team.
For not understanding all that, and for being a whiny ...
You have been judged and found wanting.
