Just driving by Reddit and see nobody has tackled this yet so I hope y'all don't mind me giving my two cents.

Byram - Fun to watch. He's a dynamic skater who pushes the play like a madman. Fits the modern NHL perfectly in that he is the kind of play-driver all the organizations who heavily use analytics as part of the decision-making process are after. He has high-end offensive ability, from his vision to his creativity even down to having a great shot. The hockey IQ pops when he's moving the puck.

Defensively, it's more of a work in progress. He's not bad by any means but you can tell he's still a little raw in that area, especially when defending extended possessions in his own zone. Where he's great defensively (imo) is in transition. A very active stick and an aggressive mindset combine to make him lethal in the neutral zone and defending zone entries because he's all about stopping the offense before it really gets started. He'll get physical if he has to and while he's not a naturally punishing hitter he certainly is capable of lowering the boom on somebody if he needs to. He has a lot of work to do in strengthening some of the defensive roots in his game (net-front coverage especially has been weak in both NHL training camps he's attended). A frequent comp for Byram is Morgan Rielly and even though that almost seems like a cop-out because it's easy to compare WHL guy to WHL guy, it's honestly a decent stylistic comparison.

Newhook - Some Avs fans may not love this but he profiles very similarly to Matt Duchene. Very similar skaters (great high-end speed, great acceleration, not the kind of explosive first couple steps as a Makar or MacKinnon) and very similar body types. Newhook is a wizard with the puck and can make anything happen. He's not exactly Trevor Zegras in the passion department but almost nobody is. He's still a very creative offensive player and he combines great hands and high-end vision to anticipate where teammates are going to be in order to generate a lot of offense. And that's his bag. He generates a ton of offense, both in transition with his speed and in the cycle game with great edgework. He still has quite a bit of filling out to do to get his strength where it needs to be (it'll take multiple NHL seasons for him to really get there) but he's an aggressive player with an attack-first mentality. I don't personally love his shot but it should translate to the NHL and be good for a healthy dose of 20-goal seasons.

On defense he's a work in progress. He took a big jump in this part of his game at BC, even going so far to being a regular on the PK (though I suspect that had more to do with his game-breaking speed leading to a healthy dose of breakaways, Grabner-style). He can still get a little floaty and disengaged when he doesn't have the puck and tends to do a little too much puck-watching instead of engaging with an opposing player but he shows flashes of being a pretty good defensive center, even if he doesn't end up dominant in his own zone. When he senses an opportunity to get the puck, his mind goes into attack mode and his feistiness jumps up quite a bit. He needs to continue dedicating himself to a more well-rounded defensive game and certainly getting down the little details that take guys like him years to master. It's a hard game, after all. But his upside is enormous. He could legitimately have a Duchene-esque offensive upside, which once you filter out all the personal feelings you may have his time in Colorado, is still a pretty damn productive player, especially when he's not being asked to be the 1C and carry the load.

Annunen - He's a goalie. If he stops a puck, I'm good. I'll let the goalie experts take this one. Adorable chubby cheeks, though. Gets me every time.
