Few topics and arguments are being argued at once. Some are general to Scheifele and some specific.
"Burning of ELC"
I liked this article:
Why Your Team Is Going To Keep 'Burning' Entry Level Contract Years (So Stop Complaining About It Already).
Don't agree with everything but the essence of to me agrees with me. If a player is ready to be a valuable member of the team, it is worth it for the team to keep.
"What makes a player ready"
Well it's a tough call here and I guess a lot of it depends on role too. A more offensive style player
may not be ready until they can play top 6 minutes. A more defensive player
may be ready as soon as they can play on the 4th line. But, similarly to above, if a player can be a valuable piece to the team, then who's to really think the player is not ready.
"Will coming up to early harm progression"
In my mind yes. We have seen the effects but every player, position and role is different. Plus, there's a difference in whether a player is being sheltered or thrown to the wolves right away. IMHO, the best development situation for a player is playing in the highest level of hockey that they can actually compete in without being a liability. In other words, if they are a NHL level player then they would most likely gain more playing in the NHL than juniors or the AHL.
Scheifele...
I think "ready"-wise Scheifele is right on the border, to the point that it would be a tough call for anyone to decide concisely. He could potentially be a valuable player to this team. I wouldn't worry about the shortened season as he'd be getting more games played up in the NHL than he'll be getting in junior anyways. I wouldn't worry about his balance/weight issues as the team won't place him in situations where he can't handle himself and all the gains there are made in the offseason anyways. I wouldn't worry about him playing on the 4th line, as that likely wouldn't last long with the likely prevalence of injuries in a shortened season, and heck he was given more TOI than the other two 4th liners (and more time than one of the 3rd liners) in the first game.
If Mark is ready he should stay and if he isn't ready he should go back down, irregardless. Scheifele may be ready and he may not be ready; I can see arguments for both and I don't think anyone could say with 100% certainty of one or the other without talking a little bit of BS. I will trust Chevaldayoff with this decision and I really don't think I'll be angry at either.
