Fair point. While I'm not nearly as down on the Oilers as many of my brethren, I think it's a fair counterpoint to say that at some point improvement has to be measured in the post season though.
The jump from 17-18 to 18-19 is 100% well done, and it's entirely possible they surpass 2019-20 given how open the Pacific is this year.
The Pacific is really, really weak this year. I think it's Vegas 1st, then maybe Oilers 2nd, and after that it's a crapshoot. However regular season success in a weak division does not guarantee playoff success, as we Oiler fans well know
