Great teams get blown out from time to time. It happens. And a bad team like the Wings can get really blown out. Even in our prime, 2006-2009, the Wings didn't play perfect every game. They took games off. Even with a hardass like Bowman or Babcock that happened. It happens.
Maybe Blash isn't getting everything he can out of this roster. But 90%+ of the performance of the roster is on the roster, not the coach.
The buck ultimately stops with the GM. Period. He's the one that assembles the roster, hires the coach. And especially in this case where by all accounts, ownership isn't that hands on with the team and lets Holland run it, it's really all on him.
If Blashill is such a significant part of the problem, then Holland is a problem in that he's not replaced him yet.
I think it just comes down to what you believe about hockey. Do you think a superior coach can take a mediocre roster to cup contender? I do not. I don't think Bowman could get this team past the first round, much less to the finals. I frankly think he'd have a 30% shot at getting them into the playoffs. I absolutely believe though that our 2008 team could have gone to the finals with just about anyone behind the bench. A team with Lidstrom, prime Datsyuk/Zetterberg, Franzen going beast mode, Rafalski. That is just insane talent.
