Over the course of two weeks in mid-September, I spent some time talking to Al Horford and various people around basketball for a profile that appears in this week's Sports Illustrated. I loved reporting it. Horford's story pulls in threads from all corners of hoops. Beyond talking to Horford himself about his culture, his kinship with David Ortiz, and the future in Boston, it also meant talking to John Calipari about coaching the Dominican national team, Tito Horford about his role in Dominican basketball, Karl-Anthony Towns about his relationship with Horford, and Brad Stevens about the Celtics' work this summer.
