Drai and McDavid are defensive liabilities for Edmonton.
That was a good video. I'd definitely make Drai in particular watch it with a coach (Woodcroft, Manson, whoever Drai trusts) instructing alongside.
If he gets pissy (I hope he wouldn't) then trade him for a haul. If he doesn't, let him absorb some of the "we have to get better" personally so that he and McD can't constantly blame management for the lack of support, and remain part of the solution.
You see in my mind, this is the issue with the Oilers right now. They no longer lack forward depth, they have depth (it may not have shown up this playoffs, but it is there), what they lack is attention to detail defensively. McDavid and Draisaitl both want to win desperately, but for too long it was "we need you to score, do your thing" and nobody has had the courage to point out the gaff's that they make when watching the puck (Nurse also a MAJOR culprit with that).
To me it's very simple, and it's been the same on any team I ever played/coached... It was originally surprising to me, but some people just don't "get" defensive awareness and it needs to be taught.
My attitude had always been "I get it, so it's pretty simple", but people are just wired differently... and what comes easy for some is mind-warping for others... so it makes complete sense that for some offensive virtuoso's, they think the game "with the puck", it leads to "get the puck" which leads to "watch the puck". And that's the schema you've got to break down so that "watch the puck" becomes "watch your man, but one eye on the puck".
And the flip side is also true... like don't ask me how to be "offensively creative", god help you! For mere mortals, the best you can get is "puck protection and puck possession" so that eventually it ends up in the skilled players hands.
My point is this: I don't see it as McDrai's fault that they don't have that defensive awareness. It isn't natural for them... I honestly believe they want to learn... I blame management for treating them with kid gloves because nobody has the guts to say "you are brilliant, but you see here... you screwed up here, here's how to avoid it next time".
To that end, it's a very tough spot to put a coach in and on successful teams, the feedback comes both from coach AND importantly from defensively aware (and RESPECTED) vet teammates. I think Smith and Keith helped with that last year and I expect Ekholm will these coming years, but there needs to be more. What this team really needs is a confident goalie who can say "on this play, this is what I need from you"... and you don't get that from a rookie and a guy who is battling depression/confidence issues (just calling it like it is).
