(1) Edmonton Oilers vs. (3) Winnipeg Jets The series matched the
Edmonton Oilers, as coached by
Glen Sather against the
Winnipeg Jets, as coached by
Tom McVie. In fourteen regular season matchups, each team won seven times. With the layoff between playoff series, Winnipeg formulated a potential game plan for Gretzky by
Lars-Erik Sjöberg and McVie to try and chase him out as often as possible so he would have to pass the puck on his backhand rather than his forehand, which is where Sjöberg would meet him. Winnipeg prevailed in the first two games in Edmonton with tight battles. 11,871 fans watched the first Avco Cup championship game in Edmonton. In Game 1,
Rich Preston gave them the lead three minutes into Game 1 on his goal before
Bill Lesuk gave the Jets a 2–0 lead on his goal eleven minutes later.
Bill Flett scored for Edmonton with 2:12 remaining in the first period on a shot from the corner that bounced of the heel of Gary Smith's stick and into the net. Preston added in a second goal with 3:36 remaining in the third period. In Game 2 (with 11,405 attending fans), the Oilers led in the second period on a
Dennis Sobchuk goal, but the Jets scored three goals, with
Willy Lindstrom breaking the 2–2 tie with 4:36 remaining in regulation. For the next two games in Winnipeg, the two teams split victories. The road team won again with Game 3, now in Winnipeg (with 9,130 attending fans) that saw eight different players score for the Oilers in an 8–3 victory; it was the first time Winnipeg had lost a playoff game since Game 3 of the
1978 WHA Quarterfinals, a streak of 12 games. On the day of Game 4, Oilers goaltender
Dave Dryden was named the final recipient of the
Gordie Howe Trophy for most valuable player in the season. Also announced was the First and Second Team honors, which saw the Jets have one player receive honors with
Morris Lukowich as Second Team for left wing while Edmonton had Dryden for First Team and four players on the Second Team with
Paul Shmyr (D),
Dave Langevin (D),
Wayne Gretzky (C), and
Blair MacDonald (RW). Later that day to 10,295 fans in Winnipeg, the two teams each scored a goal in the first period before Oilers took a 2–1 lead into the third period on a goal by
Brett Callighen.
Morris Lukowich tied the game for the Jets nine minutes into the third period on a power-play goal before
Lyle Moffat scored the go-ahead goal with 6:26 remaining in the game. Now trailing 3–1 in the series, the Oilers returned to Edmonton to a crowd of 13,308 and rocked the Jets early with four goals in the first period on their way to a 10–2 victory, which notably saw
Ron Chipperfield score five goals while Winnipeg's
Terry Ruskowski injured his shoulder. Winnipeg took out goaltender Gary Smith 10:45 into the second period for Joe Daley. 32 total penalties (26 minors) were issued during the game. 10,195 people saw what would end up being the final WHA game when the Jets played the Oilers in Game 6 on May 20, 1979. The Oilers would miss the services of
Dennis Sobchuk, who contracted food poisoning when eating a steak sandwich at a Winnipeg restaurant, while Ruskowski returned from his one-game absence, later crediting team trainer Bill Bozak for his aid. The Jets held court from the get-go, with
Willy Lindstrom giving the Jets an early lead two minutes into the game on a goal. After being up 2–0 in the first period, the Jets then scored three goals in the span of four minutes to rocket up to a 5–0 lead, with
Lyle Moffat having the series-clinching goal at 6:35 in the period. Three players led the Jets in goals for the series with four by
Rich Preston,
Morris Lukowich, and
Willy Lindstrom. This was the first and only time that the
Avco World Trophy was won by a team that did not finish first or second for points in the league. A parade was held on May 22 in downtown
Winnipeg. ==Player statistics==
