Agree with the first part of your post, really like St Louis and Colorado this year. Colorado specifically had an impressive year when you account for games lost to their top end players. With everyone healthy, my god how good can they be?
Edmonton may be deeper than last year but that’s not saying much. Yamamoto is a pleasant surprise ( understatement ) and Drai and McDavid are an incredible one two punch. But the talent drop off after those guys and Nuge is massive. I just don’t see them being deep enough to get past the Avs or the Blues.
The Oilers are a bit deeper than what I think people here believe, they were not headed to a playoff spot, maybe even winning their division by accident.
Lets look at the Blues forwards no.5-11 versus the Oilers, I'll include basically Tarasenko as a place holder as one of their top 4 forwards to be fair.
Sanford - 16 goals //// Neal - 19 goals
Bozak - 13 goals //// Kassian - 15 goals
O'Reilly - 12 goals //// Ennis - 16 goals
Sundqvist - 12 goals //// Archibald - 12 goals
Barbashev - 11 goals //// Athansiou - 11 goals
Thomas - 10 goals //// Chiasson - 11 goals
Dunn - 9 goals //// Sheahan - 8 goals
The Oilers "support forwards" scored 92 goals this season in the NHL, the Blues forwards are 83 goals for forward spots 5-11.
Now do I think the Oilers roster is aces, no, Chiarelli did a lot of dumb things but Holland has made the team significantly deeper in a year. I think the Oilers are probably more like what the Avalanche were like 2 years ago ... remember the Avs were great early in MacKinnon's career, and then had like 2-3 horrendous seasons before finding themselves again, I think the Oilers are kinda similar to that.
Definitely not a "favorite" in the West as the thread title implies, but are they better than a year ago? Certainly. McDavid-Draisaitl-RNH-Yamamoto are the highest scoring foursome in the NHL, yes, but actually their forwards 5-11 did some work this year too.
