He tries to play well in his own end at times, but totally lacks the awareness to do so. It's not like he floats around in the high slot asking his D-men to try and defend 3 guys.
I don't see his faults in the Dzone as awareness. Like you said, he's not floating around like Seguin did. He's in the right places, but he gets beat out of the corner or he loses a battle and in the second and a half it takes him to get back into the play, the other team has us in a 3on2 and makes us pay.
The fact it appears he cannot play the wing, also speaks to his hockey sense. Seriously, wing is a MUCH more simple position to play than center. I don't see how a player can play C but be completely ineffective on the wing. But than again, I don't think he can play C at the NHL level either.
I know I'm disagreeing a lot but I don't mean to be contrary. Honestly, I don't agree that he can't play wing. Some of the best games he's played in the NHL have been on the wing. I remember Julien saying after one game on the wing that if he played like that every night he'd get all the ice time he can handle. I think he's immature, and stubborn. I think he came into the league thinking he was one of the rare few that teams would make an exception for. A guy who brought so much offensively that they'd forgive inconsistent drive and the resulting defensive problems that creates. It sounded like he was coming out of that delusion this summer, with his talk of getting stronger and being better on the walls. Then he showed in camp that he could be more engaged. Now he has to show it in the regular season, or he's not long for this team. Cassidy certainly seems like he is not a fan.
