From a profile of Novak Djokovic by Lauren Collins in The New Yorker:
Part of the poignancy of sports is the mismatch they create between physical maturity and emotional development. An athlete's career is unlikely to flower in perfect concert with his self-knowledge. Imagine if politicians, or businessmen, reached the height of their professional powers just a few years after adolescence. Internet moguls do, but, unlike athletes, their tenures are open-ended.
Naturally I thought of Yasiel Puig upon reading this, although I'm sure many Dodger fans consider his growing pains more frustrating than poignant. It's a different way of looking at his development, and I can appreciate it. (Ask me if I feel the same way in October.)
