Input: Question: Which team eventually won the playoff between the Calgary Flames and the Minnesota North Stars? Passage:With USA's coverage of the 1981 Stanley Cup Playoffs, it marked the first time that there was "blanket" American television coverage of the NHL playoffs. In other words, more often than not that, whenever a game was played it was televised on a national outlet (whether it was broadcast or cable). USA however, didn't televise Game 1 of the playoff series between Philadelphia Flyers and Calgary Flames (April 16) because they were instead broadcasting a baseball game between the Pittsburgh Pirates and Philadelphia Phillies. Meanwhile, they also skipped Games 2–6 (on April 17, 22 and 24) of the Philadelphia–Calgary series because of their coverage of the NBA playoffs. USA also didn't televise Games 2 and 5 of the playoff series between the Calgary Flames and Minnesota North Stars (April 30 and May 7 respectively) because of baseball games involving the Minnesota Twins vs. the Boston Red Sox and the Los Angeles Dodgers vs. the Philadelphia Phillies respectively.
