I think we can take a lot of those guys who play an all-around game and provide leadership and find similarities to Andersson.
Despite my doing so recently, I'm always leery about player comparisons.
The Rangers hope would be that Andersson becomes a core all-around player who is very good at a lot of things, but not necessarily strike you as outstanding or elite in any one particular skill set. Talking about guys like Bergeron or Toews would be the peak, hitting every single milestone in development kind of outcome. Sounds fantastic but I highly doubt he hits that level. Below that you have the O'Reilly, Drury, Horvat, Huberdeau level and I think that is a more realistic high-end upside for Andersson, and one the Rangers would be elated to have.
The risk with a player like Andersson, if you want to call it a risk, is that if he develops there is going to be a lot to like about his game. Sometimes when you have a player who does so many things that you like, it's easy to either expect more offense out of them or over-project them. Those two elements, perhaps more than anything that Andersson can do to assist his own development, are my biggest concerns.
Already I see it creeping into conversations around here, especially as Chytil's offensive development takes off faster than most people expected - including, I would imagine, a lot of members of the Rangers hierarchy.
Andersson's game will always be about balance, no matter where his offensive game peaks. Maybe in 5 years he becomes one of the top picks in his draft, maybe 5 years from now we find he was taken too high, but either way I think we have to have a reasonable understanding of what Andersson is likely to be and what he is not likely to be. From there, we need to set reasonable and fair expectations. If he exceeds them - fantastic!
