Nowhere near the class of rookies last year, but hopefully we get a good race out of this.
Hischier or Patrick are safe bets.
It will be an exciting one to say the least - last year, Matthews and Laine were so goddamn far ahead the rest of the pack (even Werenski, yes) that it wasn't even funny after the game 30 mark or something.
I went with McAvoy. The reasoning: as for Boston's defense corps, he will have enough guys to work with (Krug, Chara, Carlo etc.) that he won't be put in a situation in which he has to handle a bigger workload than he should, but he should also be able to shine behind the others. Then you have Rask, a top 10 goalie who you can always rely on to cover some of Charlie's rookie mistakes (for more recent information about goalies making a stud rookie defenseman look better, see: Bobrovsky, Sergei). And it's not like Boston's forward group is anything to scoff at either. I honestly can't think of a better situation to be in for him in this league. Oh, and there's one thing I haven't mentioned earlier: McAvoy is quite ****ing amazing in his own right.
Other candidates:
Kyle Connor - there is a very good chance that he gets to play with a terrific set of linemates in Scheifele/Little and Wheeler, which would allow him to score a ton of goals, which is key in Calder voting. Then again, will he survive the grinder that is Paul Maurice's awful rookie deployment tactic (= in order to qualify for the top 6, you must drag an anchor and an anvil for half a year and look good while doing so)?
Clayton Keller - all I've ever seen from the guy is just pure magic on the ice. The talent he has could easily allow him to be the difference maker Arizona desperately needs. The downside to his situation is that Arizona is a team who can offer a lot of support for him.
Nolan Patrick - he's getting plugged into a lineup on the upswing and chances are that he'll play in a sheltered role behind Giroux and Couturier - sounds like a great place to be, doesn't it? Well... I think he'll be in the top 5 in Calder voting at the very least, but will he stay healthy? That's the main question now, and Flyers fans should get used to it, since that's what most would think as the main reason for him failing to reach his expectations.
Thomas Chabot - if the guy is paired with Karlsson, he's in the discussion for the Calder. The problem is, playing with him comes with people being skeptical of Chabot being a product of Karlsson, even if stats would suggest otherwise (for an example, see: Laine, Patrik with Scheifele, Mark). I'll say this though - if Chabot is left with any non-Karlsson Senator for a prolonged amount of time, I just don't see him shining brightly enough to win.
Alex DeBrincat: you can't even be sure about him sticking with the Hawks. Then again, that's what I said about Marner last year. The guy has just as high a ceiling as any rookie in this class, and given a role in which he can show off his best attributes, he can be on the brinc of becoming a star as soon as next year. What's more likely is that he is not, and as a fan of another team in the Central, I bloody hope that he busts for the sake of my well-being.
Josh Ho-Sang: If Chabot with Karlsson could be a lethal combo in regards to this topic, so could JHS with Tavares. The reasoning is pretty much the same for both rookies too.
Nico Hirschier: he might end up being up there with the best of this class, but I fear that the Devils won't be in a good enough shape for Nico to compete against McAvoy and Connor here.
