The Art of the Dealers: the NHLs Greatest General Managers is another ground-breaking effort by Matthew DiBiase. Like his first effort Bench Bosses: the NHLs Coaching Elite (the first hockey book to rate and rank the greatest NHL coaches of all time using a metrical system) The Art of the Dealers is not only the first hockey book to rate and rank the greatest general managers in NHL history; it is also the first book of sports history to rate and rank the greatest general managers of any of the four major North American sports (baseball, football, basketball, and hockey). The Art of the Dealers is based on 17 hours of interviews with NHL players and general managers (active and retired) like Lou Lamoriello, Cliff Fletcher, Ray Shero, Doug Wilson, Jim Rutherford, and David Poile who shared their insights and philosophies about what it takes to manage, build, and maintain great hockey teams. The Art of the Dealers also examines great managerial legends like Sam Pollock, Jack Adams, Conn Smythe, Harry Sinden, and Glen Sather; their great (and not so great) trades, draft picks, and free agent signings; how they discovered and hired (or fired) many of hockeys greatest coaches; their managerial methods and organizational philosophies; and their innovations that helped develop and maintain the NHLs greatest dynasties during the first century of NHL hockey.
