Took a step back this year right from the get-go. Was getting way to adventurous in his own zone both with the puck and with coverage that led to lots of turnovers/GA. And then went on a binge of undisciplined penalties, some backbreakers for the team. Add to that his offensive output plummeted.
So as
@Tyson said, once he got hurt, and they brought up Struble who played much, much better than him, they sent him to Laval to sort things out.
Unfortunately, although his offense has really exploded in Laval, he's still way too lackadaisical in his own zone. And we are absolutely stacked on LD and the way Struble is playing, I can't see him losing the starts. Struble has been our best D overall since he's come up, IMO. X will be back, though. He's only 22. We'll surely be making some trades to break-up that logjam we have on LD.
