I really think we're passed this point, already. Take a look at what Toews and Bergeron were doing in their D+2 seasons, keeping in mind that these guys were also essentially a year younger than Andersson was.
On draft day:
Toews - Turned 18 two months prior to the draft
Bergeron - turned 18 a month after the 2003 draft.
Andersson - Turned 19 4 months after the 2017 draft.
Lias was a very old draft pick. No book is fully written on a 20 year-old prospect, but these Bergeron and Toews types generally establish themselves extremely early.
These first few months in the AHL for Lias will be telling on where he's at, and where he may end up.
Agree on the last point, and I mostly agree (90 percent?) on the other stuff --- though I don't know if I ever saw Andersson in that Bergeron/Toews capacity. For me, Andersson was always more of an O'Reilly/Horvat kind of prospect. So in that regard I've tended to look more at what they've done when looking at Andersson.
Could Andersson have potentially played in the NHL last season and potted close to 8 goals and 26 points?
Maybe, probably a little less. But fairly close.
Likewise, could Andersson have played in the NHL this season and netted 13 goals/26 points --- roughly the production of Horvat and ROR in their D-2 season?
Maybe, probably a little less. Though it is worth noting that in both scenarios, the Avs and Nucks were better teams than the Rangers were last season and are expected to be this season.
Toews and Bergeron were/are legit first line centers. Bergeron fell in a stacked draft and slipped under the radar. In Toews case, he was a third overall pick, and arguably in the conversation to go second. I don't think it would be fair to put Andersson anywhere near those expectations personally. So while I really like him, I feel that's probably a bit too lofty for my preferences.
But I can't quite help but feel that Andersson could very well be playing right now if the Rangers decided to go that route. And if they did, I can't help but feel the end result is probably in the ROR/Horvat range. But I'm also hesitant to put too much of Andersson being in the AHL on him as a player right now. I think it's an organizational preference.
