Here's a crazy idea. Maybe Blashill is a fine coach for the collegiate and AHL levels, but his system, strategies and coaching technique simply don't work in the NHL. It didn't exactly translate at the international level either. His World Cup team was shutout and bounced by Finland in the first elimination round after looking mostly dominant in group play (after the initial embarrassing loss to Germany).
The Blashill line blender has rarely if ever had a positive effect. He keeps doing it.
The zone entry on the PP has never worked. He keeps doing it. They've been consistently bottom half in the NHL, except the season he had Datsyuk.
The PK has gotten worse every season since he's taken over.
Like Babcock, he doesn't adapt his strategies based on the talent he has, he tries to shoehorn everyone into playing his system, his "process," even if the guys he has are ill-suited for it.
And we're not even getting into the most common complaints about his coaching: line combos, TOI allotment, favorite pets, kids in his doghouse, etc.
His message is stale and was crap to begin with. Fire him and let Bile Mom take over for the rest of the season and pray for an upgrade at the end of the year. Worst case scenario they tank harder and finally secure at least a top 4 pick.
