That was not the point I was making.
Playing 1st line minutes is better than 4th line minutes, of course. But the bigger difference there is WHO they play those 1st line minutes with, compared to who they play the 4th line minutes with.
This all started with Chytil and the whole "2C vs 3C" stuff. Honestly, for a guy like Chytil there isn't much difference playing 2nd line minutes or 3rd line minutes as long as you have a balanced roster.
Players develop in all sorts of ways. You can't simply state "Well, let's play him 17 minutes a night and he will go from this to this in 2 years". That's video game logic. The real world doesn't work that way. It's far more nuanced. What kind of situation do they play in? Who do they play with? What zone starts do they get?
And development isn't linear. It's not a "one size fits all" thing. Some players develop better in a smaller role and then work their way up, rather than playing on the top line where they might be outmatched, while others benefit greatly from being thrown in the deep end, so to speak, playing with top players.
Also, this.
Practice and video sessions (Where they go over games, specific plays and review sequences) are massive contributors to a young player's development. Of course the NHL, and the Rangers in particular, do a very poor job showing us these processes outside the games. It would be great to get that kind of coverage if only to show people how complex pro sports is. How much time players spend on developing their game before they even step on the ice for warm-ups.
