Fletcher's efforts to match the Oilers led him to draw talent from areas previously neglected by the NHL. The Flames were among the earliest teams to sign large numbers of U.S. college players, including Joel Otto, Gary Suter and Colin Patterson. Fletcher also stepped up the search for European hockey talent, acquiring Hakan Loob and other key players. He was among the first to draft players from the Soviet Union, including CSKA Moscow star Sergei Makarov in 1983, but Soviet players were not released to Western teams until 1989. Still, the team was sufficiently improved to challenge the Oilers, who required the maximum seven games to defeat the Flames "en route" to their 1984 Stanley Cup Championship.
