Ya, that's part of Gretz's legacy. I remember hearing a long time ago about guys in that organization talking about how Gretz made them all better. I think even Mess said that. I don't think those guys would be as good as they turned out without Gretz. Coffey specifically said something about how he was way less inclined to be offensive and join the rush at the beginning until Gretz kept telling him to do so.
They spoke of how Gretz was so good in practice/demanded a high standard and it made everyone else practice so much harder, smarter and sharper with high pace and in turn a lot better players. I think one of Gretz's greatest legacies is how he help make a bunch of these guys a lot better players and thus created a dynasty here.
Wayne Gretzky 0 Cups in 11 seasons outside of Edmonton.
You're kidding yourself if you don't think you could replace Gretzky with McDavid on those 80s Oilers or even Draisaitl and still win 4 Cups.
It actually should be humbling how much help even the best players need to win a Cup.
Gretzky - nothing without an All-Star team, 1 Cup Finals with a pretty loaded LA Kings team that got manhandled by the Habs.
Lemieux - struggled to even make the playoffs without an All-Star team around him (no salary cap so easier to just collect high end players in those days).
Crosby + Malkin - Two of the best players plus good supporting cast by 09, managed to beat an aging Red Wings squad. Then nothing for many years, only able to win again when a third superstar player (Kessel) was gift wrapped to them.
No one wins anything in this league with only 3 players doing anything of impact.
