Rangers actively doing everything in their power to stunt his development.
With all due respect, I just don't see what could substantially be done differently.
As I said above, the complaints are very minor stuff. The major stuff is the level of play. It's the same thing with Kakko, and we heard the same things last year. This comes from everyone (Rangers fans, Finn's, Canadians, outside observers) that has been criticizing the Rangers, so I'm not blaming any one specific group of people for the complaints about the Rangers coaching staff with these players.
I think the reality of the situation is that these two players have not been as NHL ready as expected, and the team is not in a position to force-feed them minutes and situations. Even if they were force-fed minutes and situations, then they have numbers like Jack Hughes (16 points in 33 games, playing 18:36 per game). The numbers look better, but thats still not what's expected. More is expected, and what's needed is these kids to improve their games. The same goes for Jack Hughes with those numbers. I don't think anyone actually believes Hughes is playing that well.
If someone wants to tell me how the Rangers can help these kids improve their games, I'm all for that discussion being had. I'm also someone who thinks the criticisms of these players goes overboard at times and I'm not a huge proponent of the Rangers coach or management, but I also think these complaints people have that don't focus almost the entirety of the responsibility for the situation on the player are off.
