Poor Blash, got some of the worst rosters you could ever imagine in the modern era and still decided to coach this talentless bunch of leftovers. That's gotta hurt for him never having a chance with a decent roster and tanking his reputation as a result.
With that said, the way the team played after the good first half was definitely strange. It's hard to know if that was the personnel on defense, the goalies, or the coaching, or all of the above. When you watch the games, the structure of the team and the way they can't seem to find each other for breakouts and the multitude of odd-man rushes given has got to be related to the coaching. I don't think Blashill is as bad as most people think, but it's also hard to find positives about what he has done, so it's tough to argue against the popular opinion.
