This clause (known to the league teams far in advance) led to several trades so that teams could fulfill the requirement without exposing their lead goaltenders. It also led to anomalies such as Ray LeBlanc (the star of the 1992 United States Olympic team) being put into the only NHL game of his career so that the Chicago Blackhawks could expose him and not Ed Belfour, Dominik Hasek or Jimmy Waite. To avoid exposing any of their three goaltenders, the Washington Capitals re-signed former goalie Bernie Wolfe, who was 40 years old and last played an NHL game in 1979. League president John Ziegler held up approval of the contract and summoned Capitals general manager David Poile to Toronto to explain himself; not willing to risk being sanctioned, the team signed Steve Weeks instead.
