With the franchise deteriorating from the inside out and players wanting to leave, it's going to be less than stellar results first. I suspect the mantra in 2021-22 will center around how they have a great young core of talent that needs to develop. Certainly. But the team isn't better with, most likely, Eichel and Reinhart leaving.
I'm not sure that a new HC who uses his players' strengths is enough to overcome a drop in talent. The NHL is too competitive.
As to Munger's point...my expectations were that these owners would get out of the way (for the most part), hire good hockey people, and the team would succeed. 10+ years later ownership hasn't improved. Everything flows from there...which is why we're doing the very Billsy circa 2006-2010 era in-house hire dance.
