This saddens me. One of my best friends in the world and a guy I played football with in high school was a Stanford guy and a mentee of Bill's. They were tight. I know he thought the world of him. Prayers for his family. http://www.msnbc.msn.com/id/20039776/ "Bill Walsh, who transformed the NFL with his West Coast offense and led the San Francisco 49ers to three Super Bowl championships during the 1980s, died Monday after a long battle against leukemia. He was 75."
