The idea of an athlete writing a memoir at the height of his or her career naturally seems premature and almost futile. By definition, the book won't include all of the interesting moments in an athlete's career, so how can it really stand the test of time? There is also the danger that work lacking the perspective of a veteran looking back after a career's worth of lessons learned, combined with the fact that the author likely wouldn't want to be so imprudent as to ruffle the feathers of his contemporaries, the memoir will lack any meaningful or compelling insight (Serena Williams' recent On the Line was a work I found severely disappointing in this way).
