Argh, sorry bud. Maybe I'm not explaining this very clearly. Perhaps it's a chicken-egg argument, but I believe the problem is the whole system the whole team is unsuccessfully playing. Duchene is perhaps doing some decent things individually, but his chemistry isn't really good with anyone, and if that's the case, how can he be "playing well"? That is the problem with the whole team, IMO. There is no chemistry on any line or pairing at all. Ugly team hockey.
I'm wondering how long Roy can stick with the MacKinnon-at-center thing. It's clearly not working at this point, and I know that Roy believes it clearly must work at some point. It's part of the problem, IMO.
