Prospect Ramblings: Which League Is Best for Developing Prospects?

Welcome to my first-ever ramblings, where I’ll be writing down my thoughts on the NHL’s prospects once a week. I’ll be using the ramblings to let you in on some questions I ask myself often, regarding NHL prospects, amateur scouting and player development.


Starting off:

A little over a week ago, a trusted member of the analytics community, CJ Turtoro, tweeted this regarding the AHL:

It was accompanied by this article, which outlined the difference between the increase in NHLer and Star probabilities in prospects that join the NHL, versus the decrease in those same projections when prospects join the AHL (visualized below).
