, February 24, 2012. Stapleton played Junior B hockey with the
Sarnia Legionnaires before spending two seasons with the
St. Catharines Teepees of the
Ontario Hockey Association, winning the
Memorial Cup in 1960. With the Legionnaires he won two Western Jr. 'B' championships and one Sutherland Cup as an all-Ontario champion. Although he was a defenceman, he led the Legionnaires in scoring during his second season. His first full season was with the
Sault Thunderbirds of the
Eastern Professional Hockey League in 1960–61. Stapleton had signed with the
Chicago Black Hawks, but was claimed by the
Boston Bruins in the
intra-league draft in June 1961 and began his
National Hockey League career with the Bruins in the 1961–62 season. The next year, he split his time between Bruins and their EPHL affiliate, the
Kingston Frontenacs. Stapleton spent the next two years in the minor leagues, playing with the
Portland Buckaroos of the
Western Hockey League. He received the Hal Laycoe Cup as the WHL's top defenceman for the 1964–65 season. Stapleton was briefly the property of the
Toronto Maple Leafs in June 1965 as part of a trade with the Bruins, but he was left unprotected in the
intra-league draft and was claimed the next day by the
Chicago Black Hawks. Wearing number 7, he played some games with the Hawks'
Central Hockey league affiliate, the
St. Louis Braves, in 1965–66, but they would be the final minor league games of his career. Stapleton remained in the NHL for eight seasons with the Black Hawks, and was named Second Team All-Star three times (1966, 1971, and 1972). Stapleton played with the Black Hawks in the Stanley Cup finals in 1971 and 1973. His highest scoring season was 1969, where his 50 assists set a new NHL record for assists in a season by a defenceman (broken the next year by
Bobby Orr). Stapleton was a member of the Team Canada team at the
Summit Series in 1972. During the tournament he was a +6 and was often paired with his Black Hawks teammate
Bill White. It is believed that Stapleton is the owner of the puck used by
Paul Henderson to score the series-winning goal. Stapleton himself admits that he does not know which one of the hundreds of pucks he owns is that game winning one, though it is in his possession. In 1973, Stapleton jumped from the NHL and signed a five-year deal with the
Chicago Cougars of the
World Hockey Association (WHA) where he became player-coach, replacing
Marcel Pronovost as coach. He was a WHA first-team all-star in 1974 and won the
Dennis A. Murphy Trophy as the league's top defenceman in the 1973–74 season. Stapleton again represented Canada in the
1974 Summit Series against the national team from the
Soviet Union, this time as team captain, recording three assists in eight games. He was again player-coach of the Cougars in 1974–75, and the team struggled on the ice and financially. In December 1974, he and teammates
Dave Dryden and
Ralph Backstrom bought the troubled franchise. At the time, Stapleton also owned two small arenas in the Chicago area along with other business interests. The Cougars folded after the 1974–75 season and Stapleton was claimed by the
Indianapolis Racers, where he played for two seasons and was named a second-team all-star in 1976. When the Racers refused to honour his contract in 1977, Stapleton was transferred to the
Cincinnati Stingers, where he played one season before retiring in 1978. Over his career, Stapleton scored 337 points in the NHL and 239 in the WHA. ==Retirement==
