This is sound advice for groups and individuals. When things are no longer working, go back to basics - and work from there. The two basics in pro basketball are defense and rebounding. They don't depend on a hot hand, luck, leadership or team chemistry. They come about because of hard work, dedication to the task at hand and determination to stop every opponents' offensive move and to crash the boards to get every rebound.
I'll start with defense (or lack thereof) in the loss to the very-mediocre Bulls.
