he also mentioned the scheduled and said there are some mental mistakes happening
you don't want players/coaches to use excuses because that could actually creep into their games but as fans we can actually see what's happening and they look tired and have looked tired for a while now
I'm sure they are tired - that schedule had to have been a grind - but there is more to it than that.
Arniel also had a lot to say about the how players were not taking the opportunity to take the hard ice or shoot the puck - and he did chalk that up to mental lapses - but not just because just because they are tired. He also mentions that players who have not scored a lot recently, are making things more complicated than they need be. IOW's, making that extra pass rather than shooting - because they are slumping.
So it's fatigue, lack of confidence, over complicating, slipping off message, and so on - it's a bunch of things
