Change is typically a slow and deliberate process. It happens over time and is the result of hundreds of small individual things that came before it. For the San Antonio Spurs, change happened fast in the summer of 2018. By trading Kawhi Leonard to the Toronto Raptors, the Spurs made a massive change to what the future of the franchise would look like.
The prize piece of the trade for San Antonio was DeMar DeRozan. After spending his entire career in Toronto up until that point, DeRozan looked like a finished product.
