I've caught a bit of Dvorsky recently.
The guy is a PP savant. Would immediately be the best half-wall player we've had since Kovalev. His shooting and scoring instincts are well documented, but his playmaking really flies under the radar. He consistently makes quick, accurate passes through the box. Pinpoint saucer passes on both forehand and backhand. There's shades of Kucherov there.
I've also liked his in-zone play at both ends of the ice. His positioning is overall, quite excellent. He's got a good frame and compete level, if a little underdeveloped physically. He'll be an above average player on the boards, down low and in the faceoff dot. He's calm with the puck and consistently makes the right reads with it.
His biggest weakness is 5v5 neutral zone/transition play. He's just not a dynamic puck carrier, and doesn't really push the pace of play. Not really a threat to take the puck inside or beat a defender 1-on-1. I can see why Slaf (assertive) and Mesar (dynamic puck carrying) would compliment him very well. HIs off-puck offensive play and instincts are much stronger, at least before the play settles down in the OZ.
All in all, I wouldn't be upset taking him at 5. As he is, I don't think Monahan is a bad comparable, with higher playmaking/PP upside. If he can find an extra gear in his skating, which is only fine right now, it would really help him hit another level.
