Just a thought. Watching the youth (not so much the current crop but going going back a bit too) break into the NHL and not be able to duplicate scoring feats makes me wonder how much stock you can put into AHL numbers. I know there are other factors like role and ice time too. Tynan’s couple of games up actually got me thinking about this more. MVP AHLer but he looked pedestrian in the NHL. Amazed by the skill difference in the two leagues. I guess you still want that production from prospects and progression at every level but it doesn’t always seem like a good indicator for NHL success.
I wouldn't say it's overrated. Because quality NHL players DO produce in the AHL. It just gets misused as a predictor for NHL success.
The league is a developmental league, meaning there are many players trying to find their place in professional hockey. As such, there are mental, positional, and other lapses where you can't reliably predict that transition to the NHL.
Production in the AHL is still meaningful. It separates you from the rest of the league. And the rate/variety you can expose those lapses contributes to establishing a modicum of success in the NHL, where those lapses are often narrower in scope or frequency.
For example, the Kings had Jordan Weal in their system for many years. Skilled, decent skater. Small. From the juniors through minors, he would engage with the players by trying to check, but bounced off of them. The only way he would recover a puck from the opposition is if he snuck from behind and picked their pocket. He led the championship Monarchs in scoring. Yet his career high was 21 points in a season. No variety to his game with a niche skillset.
On the other hand, Derek Armstrong was much more successful in the AHL and NHL despite being less skilled with fundamentals. However, he had multiple ways to separate the player from the puck. He read his options better.
So yeah, on its own, AHL production without context or observation is useless. It has meaning though.
