About Glen Hanlon
Glen A. Hanlon is a Canadian ice hockey coach, executive and former goaltender. In the season's first week, the Capitals jumped to a 3–0 record but went on to lose 15 of the next 18 games (3–14–1), which lead to Hanlon's dismissal. On October 14, 1979, Hanlon allowed the first career NHL goal scored by Wayne Gretzky, who would eventually become the NHL's all-time scoring leader. Hanlon has been quoted as saying "I created a monster" in reference to allowing Gretzky's first goal. In 1978, he won the Central Hockey League's Rookie of the Year.
