I see a lot of people put Malkin as NHL comparable for Byfield but I really don't see that at all, especially stylistically. Malkin has a much better vision and slows the game down and can easily play through traffic. His game is not based on speed at all, it's mostly based on strenght/control and playmaking. I haven't seen many make this comparison but I see a bigger Matt Duchene when I look at Byfield and I think it fits his playing style much better.
Fast skater, good in transition and strong on his feet. Not very physical but doesn't get pushed around either. Great shot and will go where he needs to go to score goals. Good playmaker but it's not his best asset and likes to shoot more than he likes to pass. Both score a bulk of their goals off the rush by surprising Dmen with their speed and a quick elusive shot. He reminds me a bit of Zibanejad as well but Zibby has more presence to his game and plays a bit more of a steak-potatoes game while Byfield has softer hands and likes to play with more finesse.
I'm really interested in seeing how he adapts to the NHL and if he can learn to be more physical and not as reliant on his speed. I have to say the short stick does bother me a bit. He could play a much "bigger" game if he would use his reach to his advantage. Right now I see a big guy that doesn't play a big man game. The thing I'm worried about is that he might not change his game and that could hurt him in the NHL. Physical play is not for every player, big or small. Some small guys are way more impactful physically just because that's the way they're hardwired to play.
Nevertheless, he'll be an elite player. It's just that you have to keep these things in mind when drafting. You can't just assume a guy will be dominant physically because he's bigger or even that he'll be able to change his playing style so that he could really become one of the best players in the league. Between him and Stutzle, I think Stutzle has a better chance to be succesful next season because of his ability to control the play and slow it down in his density areas which he has already done against men and in international play. (And Byfield hasn't really excelled playing against NHL-like structured defense)
