I was hoping for the Blues starting with the 2nd round. (Not the 1st round of course, when they beat my Jets.) They had the longest Cup drought of any team. This is how the first-wave ['67/68] expansion teams have fared:
The Philadelphia Flyers won the Cup in '74 and '75
The Pittsburgh Penguins won in '91 and '92 with Mario, and since then several times with Sid the Kid.
The MInnesota North Stars relocated to Dallas (as the Stars) in '93, and won the Cup in '99.
The LA Kings won the Cup in '12 and '14.
The Oakland Seals were renamed the California Golden Seals, moved to (IIRC) Cleveland as the Barons c. 1977, and folded and were merged into the MInnesota North Stars c. 1980.
The St Louis Blues, despite their early success (with three consecutive appearances in the Finals in '68, '69, and '70) have finally won their first Cup.
Next up for futility? Buffalo and Vancouver, which entered the league in the 2nd expansion of '70/71. Both teams have been to the Finals a couple of times, without success.
I thought this was the best story to come out of this year's playoffs:
