Warriors 2 years ago were the worst team in the league with injuries. Last year they improved but missed out on the playoffs.
This year they put it all together, developed some other guys like Poole/Kumgina, got Gary Payton II for the cheap and he turned out to be an X factor, made Andrew Wiggins the player that he is this year.
Klay missing 2 years because of his knees, Steph broke his hand 2 years ago, Draymond was just the lone ranger.
When another team can develop 3 future HOF players and they win as much as these guys can, it's a very special core. Golden State and San Antonio are good organizations.
