We did tank though. If we hadn't had Lundqvist and found money in Georgiev and Strome, we would've slotted quite a bit higher than where we won the lottery from.
We didn't create a roster hoping to be the worst team in the NHL, but we sold off everything that didn't have term behind it for a year and a half, and in the midst of that we played a bunch of kids who were not really even NHL players yet throughout (Pionk, Lemieux, Chytil, Howden, Hajek).
We shifted course really quickly and threw a ton of money around signing Panarin and Trouba, re-signing Kreider. But icing one of the youngest rosters in the league for two years when the players who were bringing that average age down so much were really mediocre to bad players for the most part is what tanking teams do. That's why so many were/have been confused as to whether this team has really been rebuilding or just 'reloading' and as bad as tanking might seem historically, it's certainly been more effective than the latter.
