I don't really think there's one specific position where we need to draft. These guys are 2-3 years away from making an impact. Kreider will be nearing the end of his contract, so even LW is a position to look into.
Players that I have been focusing on for various reasons:
Andrew Cristall (LHLW)
Teammate of Talyn Boyko in Kelowna (WHL). Cristall is a talented playmaking winger who may lack size, but I really don't care about size. It's overrated in today's NHL anyway. He distributes the puck really well and is a good skater. Probably too good for the Rangers to target

Cristall is not playing in the WJC unfortunately.
Charlie Stramel (RHC)
Players with an edge. Really fits the mold for the Rangers and Drury. Not the best skater in his position but he creates offense with his fast decision-making which could make up for that slower first step. Plays for Wisconsin in the NCAA this season. Only played 1 game in last summer's WJC but will have a bigger role this time.
David Reinbacher (RHD)
Someone else mentioned him earlier but he fits that mold the Rangers have targeted with Schneider only 2 years ago. Austrian kid, which is a bonus for me having lived there, it'll be easy to connect to him as a fan. Is a 0.5 P/GP in NL this season which is very imperssive for a D-man in his draft year, already a record. Not the flashiest player but gets the job done.
Eduard Šalé (LHRW)
If you want flash, this is the guy. But he's also 6'1" so he has the frame to grow into the type of player that can grind for the puck in the corner. His skating and puck skills combine for a great offensive weapon. This guy could go as high as 5 but you never know. A lot of teams still have a skeleton-crew in terms of scouting in Europe, especially Czechia.
Nate Danielson (RHC)
Facilitator down the middle, with a good scoring touch. May not wow you with amazing plays, but he's a very solid player who does the little things well. Plays for the Brandon Wheat Kings in the WHL, Schneider's old team. Can turn into a very solid 2-way center with the right tools to develop. I'd say he's a higher end version of Bryce McConnell-Barker.
Kasper Halttunen (RHRW)
Halttunen had a quiet start to his Liiga career, but for IFK he has been good in SM-Sarja (u20 Liiga). He's been bouncing back and forth, but in a draft year that's not necessarily a red flag. He's a good passer and also a good shooter. He also scores in the tight areas, around the crease. Quite versatile. At 6'3" and 207 lbs he will pass the size-requirement for some fans

He won't be playing in the WJC this year.
I don't really do the whole ranking thing. I don't have that need to convince myself that I am a scout like so many on social media do haha. I just watch hockey games and when players catch my eye, I focus on them for a few games. But that's all this is. Just my personal preference. I left out the top guys like Bedard, Carlsson and Fantilli because there is no way we get even close to those picks.
