Oilers are only a +800 favorite which about an average top leading favorite most seasons. Colorado was a +625 favorite 2021-22, which they won. For 2022-23, they were + 425.
Penguins or Blackhawks all have had better odds sometimes in the same year going as low as +500. Detroit red wings were a + 450 in 2002 when they won and +300 in 2003. There’s literally been a large amount of teams that had better odds than Oilers to start the season. Even Tampa Bay had +675 odds to win in 2020 and this was after that embarrassing Columbus sweep choke.
Having said that, they are the favorite this season for a reason. All these comments making them sound like this is still the overrated Oilers in 2018 is laughable people still think of them like this.
