"Buddy Ryan was arguably one of the greatest defensive masterminds in NFL history and forever left his mark on the Eagles organization and the city of Philadelphia," Lurie said. "Over the last 20-plus years, I had the pleasure of discussing football with Buddy, and I always came away from those conversations intrigued by his knowledge and passion for the game. On behalf of myself and the entire Eagles family, I'd like to offer our deepest condolences to the Ryan family."
