Tim Duncan is retiring after 19 seasons with the San Antonio Spurs. Over the next several days millions of words will be written about his impact on San Antonio, on the NBA, on basketball. The Spurs have already put up a lovely career retrospective, with pictures, videos, and highlights from his every year in the league. The hashtag #ThankYouTD is trending on Twitter and Instagram. He’s retiring with what, by any reasonable estimation, is one of the greatest careers in the history of the league, up there with Kareem Abdul Jabbar and Michael Jordan and Bill Russell. During his nearly two-decade tenure the Spurs won 71% of their games. His 19 straight years of winning more than 60% is a record not just for the NBA, but also for the NFL, NHL, and MLB. Tim Duncan was drafted right around the time I entered high school, and has made my hometown team the most successful organization in American professional sports throughout my entire adult life. I’ll never, as a sports fan, have it any better than that. Thank you for the memories, Tim.
