They won a cup. Its still more than Edmonton, Carolina, Dallas and Toronto achieved with their cores- and it remains true in at least 3 of 4 cases even after the season.
But having said that... Rantanen trade was literally biggest WTF I remember.
I mean people talking Erat-Forsberg for ages, but at least there were some logic behind it- team in "win now mode" trades for player who they think increases their chances of winning now. TBH, if Erat hadn't gone to shit almost immediately (management has zero control over such things), that trade wouldn't look so bad.
Here I don't see ANY logic. And its kinda karmatic that he was the player who contributed most in their elimination- textbook case of getting punnished for bad decision.
