If it's one good year followed by one year of regression, I'll take a more steady rebuild.
What came before McDavid is irrelevant. By trading Hall we structurally placed this team's future in the hands of Lucic/RNH/etc.
That's 3/5 of your top players that are OK with mediocrity. You're not going to have a great team with that type of a roster build.
I'd rather have kept the 3 studs that bring it every night, and gradually add to them as time goes on if need be. Hamonic would've been available, Russell was available for nothing, other D would've emerged. It just would've taken a little longer.
As McDavid and Draisaitl mature, WITH Hall our offence would've developed more along the lines of Toronto. McDavid-Hall-Draisaitl-Klefbom got what? 6 games to play together?
