I disagree with your assessment. Mikey Anderson got stuck out there more than a few times. St Ivany was often a train wreck though. I thought Samuelsson was ok.
I remember one shift where that happened (not counting the end of the game), Samuelsson was out with him.
Mattias doesn't make the "glaring" mistakes, but he made at least a half dozen weak clearing attempts yesterday which failed and resulted in more zone time. I don't expect him to make the pass out of his own end as that isn't his game, but if you're going to try to get the puck out off of the windows, you better make sure you get it out.
