In exhibitions that year, Soviet club teams went 5–3–1 against National Hockey League (NHL) teams and, a year earlier, the Soviet national team had routed the NHL All-Stars 6–0 to win the Challenge Cup. In 1979–80, virtually all the top North American players were Canadians, although the number of U.S.-born professional players had been on the rise throughout the 1970s. The 1980 U.S. Olympic team featured several young players who were regarded as highly promising, and some had signed contracts to play in the NHL immediately after the tournament.
