True. The argument for a new coach concerns the need for a fresh voice and thus to turn the page on a horrible disaster, the need to avoid MT going stale and therefore producing yet another disaster, and perhaps the idea that a season like this one is simply unacceptable, and therefore someone has to pay.
It can't be based on the 'blender,' or the idea that the coach tends to prefer veterans, emphasizes defence, likes things low-risk, or makes specific lineup or line-matching decisions that some fans disagree with. The characteristics are true of almost all modern NHL coaches.
As for Therrien putting players in roles for which they're not suited, I see that more as a symptom of a shortage of talent up front. Weise got time in the top-6, NOT because Therrien had a hard-on for him, but because we lack legitimate top-6 FWs. Period.
