I think right now he is battling to find his confidence. A player of his style is always going to be a little frustrating when it comes to turnovers because he has the puck on his stick so much. The biggest difference between the end of last season and the start of this season is that he is putting himself in more difficult situations to escape and it's leading to more turnovers.
Upon entering the zone he isn't attacking my using the middle of the ice or using his speed to go outside as much. He is curling back nearly every time, and while it can be a good option he is doing it so often the opposition is all over it. Against Minnesota they were all over it and just stuffed him on the entry.
I think his lack confidence to start is reflected in his shot totals. In the first 9 games he had 12 shots on net with just 6 points and points in only 3 of those 9 games. He maybe turning the corner however. He has 18 shots in his last 5 games with 7 points in that span, with a point in 4 of those 5 games. Last year was a similar story with his start. He again had 12 shots in the first 9 games, the move the center helped him but I wonder if it takes some time to get going in a fresh season.
