I mean the fact that Miller is the most productive player on that list kind of says everything.
Career highs in points - Miller 72 (56 w NYR), Stepan 57, Callahan 54, Dubinsky 54, Kreider 53, Buch 46, Fast 33.
The Rangers do not exactly have the best track record of developing elite forward talent. To be fair, up until recently they have not had the draft capital to do so. I believe Lafreniere and Kakko will blow anything previous out of the water. But I get why people have varying levels of confidence based on what they have historically seen from this franchise over their lifetimes.
