If you want to have faith that this is the year they break through, that this team is different, etc. then everything they've done tonight suggests the exact opposite.
They basically checked every box of teams past: Defensive breakdowns, bad penalties, lack of urgency, shaky goaltending, costly turnovers, forwards not supporting pinching d-men.
Of course they can come back and win this series, but they are going to have to overcome whatever it is they have lacked and whatever paralyzes them in clutch moments for the past 5+ years very, very quickly.
