Oh, I bet you're right on that. He's such a good player; it's must be injury. I would love to see him partnered with a gorilla-type D man. Too bad we don't have one of those guys on the back end.
It just looks like a lot of his mistakes are of the "oh I can get to that puck. Oh crap no acceleration now I'm screwed, type of mistakes." What makes it worse is he also doesn't seem to have any recovery capability either. So to me he's either hurt or he really lost a step during the off season. So I choose to believe injury because losing a step at 30 seems unlikely.
Of course it is possible that he really is completely confused on the system but given he has always shown great hockey IQ I find that hard to believe as well.
And he also missed time in camp with injury.
