Edmonton got it done because they have a better team right now. We know what it looks like when Drai/Mcdavid have mediocre support depth, a weak defensive core, and suspect goaltending on par with the current iteration of the Leafs - we watched them get punted by a weak chicago team and swept by the Jets for those reasons just a few seasons ago. These same media guys using the Oiler's success now to bludgeon Leafs for their poor performances were at the time openly speculating(or more accurately, gloating) that Mcdavid/Drai were regular season allstars who would never achieve any playoff success, especially after the winnipeg series where they struggled to create offense.
But hey, if leaf media want to continue to badger their star players because they can't will a flawed roster of pretenders past superior opponents in the first round every year, I'm all for it
