One indication of that talent: Seven Oilers -- forwards Gretzky, Jari Kurri, Esa Tikkanen, Mark Messier and Glenn Anderson, defenseman Paul Coffey , and goaltender Grant Fuhr -- were named to the 25-man NHL team that faced the Soviet Union in the two-game Rendez-Vous '87 exhibition series in Quebec City in February.
But the Oilers waged a season-long battle in 1986-87 against a memory: their shocking elimination the previous spring by their most bitter rival just down Alberta Highway 2, the Calgary Flames, in the Smythe Division Final.
1986-87 Edmonton Oilers roster
After winning the Stanley Cup in 1984 and '85 and finishing with an NHL-best 119 points in 1985-86, the Oilers had sought an extended run of championships. But the Flames ended their dream in a series widely remembered for the winning goal in Game 7, scored when Oilers rookie defenseman Steve Smith accidentally banked the puck off Fuhr's leg and into the net.
The defeat stung ferociously.

As Gretzky recalled, returning to the Final in '87 became the players' sole focus.
"From Day One in training camp, [the season] was like a blur -- the exhibition season, the regular season and, for that matter, even the first three rounds," he said. "It was, 'All right, OK, we've done this. Let's get the Final started right now.' Because that was the only thought we had in our minds among the entire group."
General manager and coach Glen Sather tweaked his roster. He shifted Marty McSorley from defense to forward (taking Dave Semenko's spot playing with Gretzky), then added defensive depth by acquiring Reijo Ruotsalainen and Craig Muni in October and promoting Jeff Beukeboom.
Sather's biggest move, however, was getting forward Kent Nilsson from the Minnesota North Stars prior to the NHL Trade Deadline.
The Oilers knew Nilsson as perhaps their most skilled opponent when he played for the Winnipeg Jets in the World Hockey Association and then the Flames. As Gretzky said: "Glen meant real business. We knew [Nilsson] was a tremendous team player and very unselfish. We were so excited."
Sather put "The Magic Man" on a line with Messier and Anderson.
"He fit perfectly," Gretzky said.
The Oilers' focus on the Cup didn't prevent them from finishing atop the League in the regular season, and they remained the most potent offense in the NHL for the sixth consecutive season, scoring a League-best 372 goals and averaging 4.65 per game, roughly one goal per game higher than the League average of 3.67.
