Originally the property of the
Toronto Maple Leafs, the young goalie played seven games for the Leafs in the
1960–61 season. Picked up by the
Montreal Canadiens in the inter-league draft the following season, Maniago underwent a lengthy apprenticeship in the minor leagues, spending the better part of five years on the farm. The high point of his years with Montreal was a 14-game stint in relief of the ailing
Jacques Plante during the
1963 season. He had a sparkling season for the
Minneapolis Bruins of the
Central Hockey League in 1965, winning the league's most valuable player award, after which he was dealt to the
New York Rangers. Maniago competed against
Ed Giacomin and
Don Simmons for the starting goal position in
1966, playing 28 games for the last-place team. On March 12, in Chicago, he allowed the
Black Hawks' star left winger
Bobby Hull's 51st goal of the season, the first time in league history that any player had scored more than 50 goals in one year. After the game, he insisted that Chicago's crafty forward
Eric Nesterenko had interfered with him during the play: "Nesterenko lifted the blade of my stick, and the puck went under it." Giacomin firmly won the job the next season as the much-improved Rangers made the playoffs, and Maniago played in just six games as his backup.
Minnesota With
expansion arriving the next season, Maniago had his opportunity. He was the first draft choice of the expansion
Minnesota North Stars on June 6, 1967, immediately becoming their number one goaltender, a job he kept for the next nine seasons. His play led the North Stars into the playoffs in five of their first six seasons. In his first season with the North Stars, he had career highs in wins and shutouts while leading underdog Minnesota into the 1967-68 West Division semi-finals. The North Stars struggled the next season, finishing in last place and missing the playoffs. Unable to find a suitable goalie to help Maniago with the workload (the other goalies the team tried went a combined 11-35-16 in Minnesota's first three seasons) the North Stars obtained
Gump Worsley's rights from the Canadiens on February 27, 1970, talking him out of retirement in
1970. The late-season addition rejuvenated the struggling team, who finished strongly, ending up in third place. Over the next three seasons, the tandem led the North Stars into the playoffs, including an appearance against Montreal in the
1971 semifinals. In this series, Minnesota was the first expansion team to defeat an
Original Six team in a playoff game, beating the Canadiens twice. Starting in
1974, the fortunes of the Minnesota club sagged, as did Maniago's play. Worsley's retirement that season left him as the sole experienced goalie on the struggling team. After the
1976 season, he was traded to the
Vancouver Canucks for
Gary "Suitcase" Smith on August 23, 1976, where Cesare for his two final seasons. ==Legacy==
