I just talked about this in another post, but he's sending the message early to Drouin and the entire team, not to get comfortable. They have expectations again this year, and he wants them playing the right way.
He hasn't been playing as poorly as people here suggest. This place is just so over the top with it's reactions. Him leading the team in high danger chances doesn't come as a surprise to anyone. We've all seen him get a ton of grade A chances, but he's just not finishing them.
That's concerning about whether his wrists will ever improve enough or if he will always have the same problems with his shot, but he could also break out of his slump one game and start putting up numbers. This is not an easy system to adjust to. It takes lots of time for everyone.
The main thing Bednar doesn't like isn't the lack of production. It's the lack of forechecking. That's a requirement for every forward for his system to work and Drouin hasn't been doing it consistently. This is an early message as to how big a priority it is.
