A successful coach in the minors, Harry Sinden
took over the helms of the Boston Bruins at the tender age of thirty three. Quickly, under his guidance and an influx of talent, the Bruins turned around and won two Stanley Cups. Despite those elite championships in the National Hockey League, it was his coaching of Team Canada in the 1972 Summit Series, where the Canadians won in a grueling eight game series where he was considered at this best. Sinden would later take over as the General Manager for Boston and managed to continually ice competitive teams.
