my personal takes...
team overperforming compared to the pre-season expectations (and the past years results): Vancouver Canucks, definitely the biggest surprise of the year
teams doing better than expected, but nothing special: Winnipeg and Nashville
teams heavily underperforming (and basically out of the playoff race): Pittsburgh above all, then New Jersey
at a lesser extent, also Minnesota, Seattle and Calgary also didn't match the early predictions
the defending champions Vegas are also having a modest season, but they had been injury plagued and however they're still going to the PO, where they might be very difficult to beat
the Chicago Blackhawks showing how difficult is to rebuild a team from scratch, even after drafting a generational talent like Connor Bedard (also because of a mangement not doing well with the other tech choices and too many injuries to some key players, tbh)
individual efforts: Auston Matthews chasing the highest goal scoring performance since many, many years; the race for the scoring title between Kucherov, McDavid and McKinnon, all 3 reaching numbers rarely seen in the 21st Century
but above all, the year in Canada has been dominated by the scandals surrounding the game of Hockey, both among the professionals (5 players charged with sex assault accusations) and the youth system (so many allegations to the so-called coaches and educators, lots of attempts to hide all the dirty stuff at the top level of Hockey Canada followed by resignations and dismissals of many propminent officials)...
all in all, not a great year for Hockey in Canada
