The paragraph primarily focuses on the role of enthusiasm in achieving one’s dreams, particularly in the context of teamwork and coaching. By describing Coach Setliff’s unconventional strategy of placing players in mismatched positions for a single play, Pausch illustrates how this approach, driven by enthusiasm and a sense of freedom, can lead to unexpected success. It highlights the importance of stepping outside one's comfort zone and embracing spontaneity, which can elevate performance and influence outcomes positively. This example demonstrates that enthusiasm can empower individuals to achieve their goals and contribute to the successes of others, ultimately supporting the wider theme of achieving dreams both personally and collectively.
Therefore, the best answer to how the paragraph develops the central idea is: It uses a story to show how enthusiasm is important to achieving dreams.
