Originally a forward, Vadnais was shifted to defence in his final year of junior hockey with the Montreal Jr. Canadiens. In his first NHL training camp, he made the Montreal Canadiens lineup for the 1966-67 season. While the Canadiens were initially successful in not exposing Vadnais to the 1967 expansion draft, he was left unprotected after the 1967–68 season and would be claimed by the expansion Oakland Seals in the 1968 NHL Intra-League Draft.[1] He became the Seals' captain at the beginning of the 1971-72 season but was traded mid-season.[2][3]
On February 23, 1972, Vadnais was acquired by the Boston Bruins[3][4] in an attempt to bolster their blueline for a Stanley Cup run. The Bruins outbid Vadnais' old club, the Canadiens, to secure his services. The move paid off and Vadnais headed the Bruins' second defence pairing behind Bobby Orr's first unit, which helped the Bruins capture the 1972 Stanley Cup.[5]
Vadnais was involved in the November 7, 1975 blockbuster trade that sent him along with star forward Phil Esposito to the New York Rangers for Jean Ratelle and Brad Park.[3] Vadnais went on to play seven seasons for the Rangers and one for the New Jersey Devils before retiring in 1983.[6] Along with Wayne Cashman of the Bruins and Serge Savard of the Winnipeg Jets, he was one of players from the NHL's pre-expansion Original Six era whose NHL career lasted the longest; the Bruins and Jets both made the 1983 playoffs, extending Cashman's and Savard's careers into that post-season.
Vadnais played 1,087 career NHL games, scoring 169 goals and 418 assists for 587 points, as well as adding 1,813 penalty minutes. In his best statistical season (1974–75), he scored 18 goals and set career highs with 56 assists and 74 points. Vadnais participated in six NHL All-Star Games and was a member of Team Canada at the 1976 Canada Cup (but didn't play in the tournament) and 1977 World Ice Hockey Championships.[2] In 1972 Vadnais was arrested in a case of mistaken identity while the Boston Bruins were on a road trip in Philadelphia. FBI agents were convinced that they have found their suspect from a bank robbery that had happened earlier that afternoon. Vadnais looked very similar to the robber. Vadnais eventually let out of custody and given an apology.[7]
Coaching career
Vadnais joined the Rangers' coaching staff as an assistant for the 1983–84 and 1984–85 seasons. This was followed by one season as the head coach of the Quebec Major Junior Hockey League's Verdun Junior Canadiens, after which Vadnais left hockey for good.[8]
Personal
After hockey, Vadnais worked as a real estate agent in the Montreal area. His wife, Raymonde, died of cancer in 2004; they had one daughter, Michele.[9]
Vadnais died of cancer on August 31, 2014, at the age of 68.[10]
