That's not what I'm saying. Hell, it's probably even likely that you're right and they're wrong. Edvinsson may be ready to jump in right now. But generally speaking, the NHL is not a learning league. It's pass/fail. It's why veteran players around the league continue to have jobs. It's why teams like the Edmonton Oilers pre-McDavid flopped hard even though they had undoubtedly more natural talent than most in the league.
You're free to be of the opinion that he's ready to go and he'll pick it up as he goes along. It's just wishful thinking because he looks as good as he does.
What I am saying is that even if you don't agree with how they're doing it, there is logic to starting a guy like Edvinsson in the AHL and "He'll learn and pick up the game as he goes along in the NHL" is not a good argument to keep him up. I don't always agree with what the Wings do. I do attempt to see the logic they're using in making their decisions though. And I get starting Edvinsson in the AHL to dominate and be groomed for running a D pair by himself.
I want more of a reason to keep Edvinsson in the league than "He's better than *insert bottom pairing D men". It's the same thing that I argued about when people lost their minds about Joakim Andersson being called up instead of Anthony Mantha in the Wings last playoff run. I want a guy to be ready to play the role I'm optimally looking at him for... because this team is bad. When you're the 01-02 Wings, you can start Pavel Datsyuk on the 4th line and it'll work fine because you need the absolute best players to make an immediate material impact. The Wings of 22-23 don't need that right this second at the risk of overexposing a kid.
He'll learn in the NHL is only the argument to those saying he's not polished enough yet. Everything he can theoretically learn in the AHL he can learn in the NHL better and quicker because the resources are better.
The main argument for keeping Simon in the NHL is that he's better than all but maybe 3 defensemen we currently have on the roster. There is zero reason he shouldn't slot into the 2nd pairing right now.
It's just a convoluted mess of arguments.
Point. - He's not good enough for the 2nd and we'd lose points that we need to compete for that playoff spot.
Rebuttal - Ok, put him on the 3rd pairing because he's better than what we have down there.
Point. - He won't learn getting 3rd pairing minutes.
Rebuttal - Ok, put him on the 2nd pairing.
Point - He needs to learn all these things to be the best player he can be.
Rebuttal - Ok, the best resources and teachers are in the NHL.
Point - Even Mo went to the AHL.
Rebuttal - Which at 18 coming out of the DEL was a step up. 19 coming out of the SHL is not a step up.
Point - Why subject him to a bad team in transition?
Rebuttal Then why would it matter if he plays on the 2nd pairing getting NHL experience in a low pressure situation since the points don't matter?
