The Spurs are using a very simple play to get good shots in preseason.
The Spurs' offense is anything but mechanical. They use sets as a way to start their attack, but how the play develops is not set in stone. Playmakers are allowed to read the floor and make decisions and everyone is expected to be able to adjust to several options. Some of the sets are more complex than others, involving off ball action, hand offs and precise cuts. Others are much simpler, like the Spurs floppy play that has been getting a lot of run in preseason.
