I get it, he's your guy. But getting salty at legitimate criticism doesn't change the fact that he blew it.. He can play responsibly 98% of the time, but if the time he chooses to peel off is when Draisaitl is flying down the middle of the ice on his way to an OT winner, then he needs to be held responsible.
FYI, I've watched most of Philly's games against Calgary and Edmonton, and bits of the game against Vancouver. Considering that encompasses Michkov's entire career so far, your assertion couldn't be any more false. This is his first error that cost them a game, but again, we're only 3 games in. If you want to make the argument that the good outweighs the bad, I'll listen, but if you're going to pretend that there is no bad, well, keep your head in the sand if that's what you want to do - it's your life.
