In 1973-74, Hull led the Jets with 53 goals, but the Jets fell to 4th place, and fell in the playoffs to Houston in the first round. So, in 1974-75 Winnipeg became the first club to actively scout outside North America. The team signed several Scandinavian players to contracts, but missed the playoffs.
Bobby Kromm was hired as coach in 1976, allowing Hull to return to the ice full time. Hull led the powerful Jets to a 52-27-2 finish, first place in the Canadian Division. The team then ran through the playoffs, defeating Edmonton amd Calgary before sweeping defending champion Houston to win the AVCO Cup. The club slipped in the standings slightly in 1976-77, finishing second behind Houston, but again made the finals, defeating San Diego and Houston before falling to Quebec in the finals. Ironically Quebec was the same team that had bombed the Jets earlier in the season 12-3 after the Jets returned from Europe. Winnipeg spent some time at the Moscow Izvestia Cup Tournament in December 1976 as a reward for winning the AVCO Cup in 1975-76.
As the WHA began winding down, after the 1977 merger talks had failed, the Jets once again showed that they were the class of the WHA. Led by newcomer Kent Nilsson, the Jets finished in first place. A phenomenonal offense had netted the Jets 381 goals on the season, and thel lost only once in nine playoff games, beating Birmingham and New England to win their second AVCO Cup.
in 1978-79, the WHA's final season, the Jets picked up several players from defunct Houston to make up for losing Ulf Nilsson and Anders Hedberg to the NHL Rangers. Finishing third in the league, they beat Quebec and Edmonton to take their third AVCO Cup, and ending the WHA's history with a 7-3 win over Edmonton in Game 6 on May 20, 1979.
The merger with the NHL was finally approved in 1979, and Winnipeg, Quebec, New England, and Edmonton were admitted to the NHL for 1979-80.
