Stud: Zibanejad - he and Panarin are going to be a deadly duo together since they're both so good at driving through defenses and opening up lanes.
Breakout: Skjei - he'll have a rocky start and have people clamoring for his head, but I think we'll see him round his game out and solidify his status as a solid 2/3D. He'll never be a true top-pairing dman, but I think he was better than the consensus opinion from last year would lead you to believe. He'll have incredibly better d-partner options this season, and I think all of them allows him to serve as a more defensive-minded option. His biggest issue is trying to play as a Girard/Werenski type, but he just doesn't have the offensive skill to do so. Letting his partners pinch and try to play deep will help him clean up a lot of the dumb, unforced errors he makes in the offensive zone.
Scrub - Namestnikov - wanted to go Fast here, but I'll give him the benefit of the doubt regarding his injury status last year. I like Names, and I'm aware that he has strong defensive impacts as a bottom-6 forward. What bothers me is that while he does has really strong skating ability and puck skills, he just plays like he's dumber than a door nail most of the time. I think we'll see him elevated in the lineup when some rookies start faltering, but we're ultimately left disappointed with what we get for him at the deadline. Altogether, he'll be a very forgettable Ranger 5 years down the road.
Other candidates I considered:
Stud: Panarin, Hank - no one else really has shown they can hit this status
Breakout: Georgiev, Lias, Buchnevich, and Lemieux - Buch more than the other two, but I've really liked what I've seen from this trio this preseason. I hope they can carry it into the season.
Scrub: Chytil and Smith/Staal - Chytil is only here because I can see this being a year of stagnation with him. He's being tasked with a lot, and I don't know if we'll see a way for him to be managed to his best potential.
Smith/Staal - 2 years remaining, $20M+ left.
