From what I've seen, skating seems to be an asset more than a problem. You can clearly see that once he gets going, he has separation speed and uses his body well to protect the puck from D and at times he even leans on the defenseman to cut to the net. He might appear slow because his first few steps are a little choppy and being a taller player, their strides are longer and less frequent so it's not the most visually pleasing.
Overall, I like this pick. He seems like he was due for a monster USHL season after putting up over PPG as a 16-year-old but the kid was hit with Covid and put on hold for a few weeks then had to deal with the constant uncertainty and game cancellations that probably held him back from getting into a groove. Every pro athlete thrives off of consistency in their lives and certainly, the lack of consistency affected him quite a bit in the beginning but he closed out his season strong putting up nearly 1.6-1.8 PPG pace over the last 15 games or so leading into the playoffs. That seems to be well on track with the expectations most had after his ppg season. I think this has the possibility to be an absolute home run pick for us. He just needs to work on keep getting stronger and perhaps become a little more physically assertive. He seems to have that elusive behavior similar to Ilya Mikheyev where he thinks he's 5'7 and able to sneak by defenders along the boards instead of just trucking players with their 6'3 frames. If he pans out, I think we have a pro-ready player by as early as 2023 who can step into our top 6 and provide much-needed size, finishing, and skill. I really don't see a ton of Hyman in his game other than his versatility in being able to play all situations. Their playing styles are very different. Zach initiates and seeks out contact quite often, whereas Knies seems like he's more calculated in that aspect. Knies also seems like a much better skater than Zach and has an NHL shot vs Zach who relies mostly on garbage goals.
This kid gives me Brandon Saad vibes. Big player with, good hockey IQ, good hands, good shot, good but not amazing skater, is not overly physical but can hold his own. Overall I think he will be a very useful middle 6 guy. The one thing he does that Saad does not and did not is PK. I think that bodes very well for him.
