Boston is no doubt a Cup favorite - but no team in history has every been invincible. I present the 1986 Edmonton Oilers as exhibit A.
2019 Lightning lost to Columbus in Round - 62-16-4 record in reg season
1996 Red Wings lost in the Conf finals to Colorado - 62-13-7 record in reg season
2000 Blues lost in first round - 51 - 19 - 11 - 1 record
2006 Red Wings (ah the memories) went 58 - 16 - 8 in the reg season
2022 Panthers lost in the second round - 58 - 18 - 6 in the reg season
Of course, there are plenty of examples of teams that crushed it in the regular season that went on to win it all.
Of the 30 best all time regular season winning percentages - 14/30 went on the win the Cup. I personally think the Oilers match up the best against Carolina or Toronto from the East...so here's hoping the Oilers can take the Western Conference and get a bit of luck. Skinner is a real wild card. I think McDavid and Draisaitl will go nova again, but can the D and goaltending hold up? I think a healthy Nurse and the addition of Ekholm give us a better chance against a team like Colorado. One of Nurse of Ek can be on the ice against Avs elites and the Avs aren't quite as healthy or deep as they were last year.
