The east is weaker than years past.
Washington has a great record but how good are they really? Leafs, Panthers, Lightning, Bruins, Rangers are all worse, the Canes don't seem quite as good either. The Devils are much better and some of the bottom feeders are a lot better but I'm not seeing any elite teams there outside of the defending Cup champs and possibly Carolina and New Jersey.
Meanwhile in the west it's a bloodbath. The Knights, Oilers, Stars and Avs are all beast teams with lengthy playoff winning pedigree, might be the 4 best teams in the NHL. The Jets and Wild are having great seasons albeit with less pedigree than the aforementioned 4 but are right in the mix with those 4 and the Kings are always a pain in the pass, really good regular season team. The west is where the strength of the league is this year.
