Yeah, it's definitely a risk. But his tools (size, skating, tenacity, shot and skill) are really tempting.
Button isn't high on him, but a lot of other publications are.
Seems like it was a tough year for Zacha personally. First year in NA, injured, couple suspensions, etc.
If his brain eventually catches up to his skills you have a top line goal scoring "skilled" power forward who has the ability to dominate games.
If not, he can still be a good middle 6 player who would probably piss a lot of people off in a fanbase because of the inconsistent play.
Overall, he's a guy I'm definitely intrigued by. He seems to be more naturally talented offensively than Crouse.
