Eleven Rings: The Soul of Success by Phil Jackson and Hugh Delehanty:
The triangle gets its name from one of its key features—a sideline triangle formed by three players on the “strong” side of the floor. But I prefer to think of the triangle as “five-man tai chi” because it involves all the players moving together in response to the way the defense positions itself. The idea is not to go head to head against the defense but to read what the defense is doing and respond accordingly. For instance, if the defense swarms Michael Jordan on one side of the floor, that opens up a series of options for the other four players. But they all need to be acutely aware of what’s happening and be coordinated enough to move together in unison so they can take advantage of the openings the defense offers. That’s where the music comes in.
