Craig Sager died on Thursday at 65 after a long battle with cancer. The broadcaster was one of the most popular figures in the NBA, and the league quickly took to Twitter to express condolences. Sager, who was randomly a part of baseball history when he got his start, was famous for his humorous battles with Gregg Popovich, and the Spurs coach was obviously shaken by Sager's death. You'll read a lot of tributes today but I recommend this cover story, The Bright Side, by Lee Jenkins from earlier this year.
