Nichushkin was stuck in his own zone because his line was put on the ice in defensive situations. And he was playing with third line guys. You honestly think Nichushkin is stuck in his own zone playing on the top line in offensive situations?
As for what you wish the two players could do better, Cole is the finished product and is more or less what he is. His hands aren't all of a sudden going to become really good. Nichushkin is on a huge upward development curve. I don't worry about the things he doesn't do well, because he can significantly improve them. I do worry about Cole's because he likely won't.
I'm not even saying Nichushkin should get put on the top line permanently, I just think he should get more shifts there, and I don't think Cole helps that top line maintain as much possession as they should be maintaining on offense. Nichushkin is just flat out more skilled, and I want to see our most skilled guys put in situations for them to succeed, or at least given the opportunity to, regardless of age or experience. This team isn't going to be a scoring machine this season, I think that's obvious.
But it's only two games in, this is probably more of a conversation if the situation maintains 15-20 games in.
