[1] Wilkins was signed by the Boston Bruins as a teenager and came through their junior system where he was a teammate of Bobby Orr and Wayne Cashman with the Oshawa Generals.
He was recalled from junior to make his NHL debut in 1966–67, playing a single game for the Bruins, and turned pro the following season.
He would spend most of the next three seasons with the Oklahoma City Blazers, Boston's top minor-league affiliate, but found it difficult to crack an increasingly deep Bruin roster.
By the 1969–70 season, Wilkins was a dominant defender in the CHL with Oklahoma City, finishing the year with 52 points and 204 penalty minutes, and he would receive his big break when he was selected by the Vancouver Canucks in the 1970 NHL Expansion Draft.
Wilkins' NHL career came to an abrupt end when he jumped to the rival WHA for the 1976–77 season to play for the Edmonton Oilers.
