Philadelphia 76ers coach Brett Brown, who endured the ultimate culture shock after leaving the San Antonio Spurs to take on a monumental challenge of leading the Sixers, calls in to chat with the NBA A to Z guys Sam Amick and Jeff Zillgitt to discuss the pain of losing and the joy of (recent) improvement. From his take on embattled rookie Jahlil Okafor to the timeline for this Sixers rebuild to his relationship with Spurs coach Gregg Popovich to reflections about his upbringing as a Davy Crockett of sorts in his hometown of Portland, Maine, Brown is honest, entertaining and insightful all the way through.
