[This] book argues that winning teams are not always the ones with the best athletes. Rather, they are the teams that are best prepared, not only physically but especially mentally. According to this view, such teams exhibit a strong sense of belief, an unshakable character, and a foundational grit. Through stories and case studies, the authors explore common characteristics of legendary athletes and coaches, showing that the best players do not always make the best coaches. Sullivan himself, for instance, was not a volleyball player in college, and Bill Belichick was regarded as a better lacrosse player than football player at Wesleyan. But as argued here, the lack of an impressive athletic resumé may have driven each of them as a coach, making each aware that failure instructs more than success, supporting the authors' premise that encountering obstacles can lead to creative thinking.
