We were a good team... in the regular season. If you're not good in the playoffs it doesn't matter how good you were in the regular season. And those Stanley Cup winning vets were easily pushed aside by Vegas.
If the Oilers make the playoffs but don't win a playoff round, do you consider that a successful season?
It's easy to forget that the Oilers were a non-playoff team 92 regular-season games ago. Since hiring Holland (and Tippett) the Oilers are 51-32-8. That has to be seen as serious progress. The fact that we're in a position where we can reasonably talk about the Oilers being a comfortable playoff team at all has to be seen as serious progress.
I don't really think any discussion about the Oilers' playoff performance makes sense at all. There haven't been any playoffs to judge. A play-in best-of-5 played after a 5 month layoff in August, with one warm-up game, is so inherently random and muddled that it's not worth thinking about beyond the obvious disappointment. It's certainly not something you make any actual roster judgments based on. Not if you want to actually key-in on things that will matter when hockey is somewhat normal.
TL;DR - I have no reason to think about the Oilers playoff performance and neither do you. The Oilers are a much better team in the less-than-100 games Holland has been our manager and that makes a thread like this premature and silly at best, and cringe worthy at worst.
