The Zetterberg Era
Ball Hockey Sucks
Let me elaborate it a bit.
The more one player dominates at a level that is pretty far from the top level (Junior level is always a lot different thing than NHL level), the more comfortable they become. The environment isn't really challenging and it doesn't force you to do everything in order to be better, more advanced. That's especially the case if the player isn't exactly the most hard working type of guy (on or off the ice). In addition to that, being in the junior level, when it isn't really challenging enough, can imprint some patterns that are typical in junior level but not desirable at all at the pro level.
That's the most important reason why the Sabres have been so hesitant to but Grigorenko back to the juniors. Grigorenko may not have been able to play in a role that is most suitable for him, but his eyes has been totally opened to the fact that the level of effort he has had, is not enough at all. That fact is a lot more important for his developement than putting up big numbers in junior level.
Would be more important if you hadn't noticed all of his coaches this year are saying he is working on his game. Mantha himself is more committed to certain aspects and has said as much. Sure this can be a concern for some people, but this doesn't really paint the picture of what is happening with Mantha. Yes he is dominating, but he is working on areas that he needs to work on in the process. Sutter referenced one of the things he really liked about Mantha was his willingness to be taught.
It might be that what is happening with Grigorenko smooths out and works out for the better after a bumpy beginning. However, that isn't the plan with Mantha.
Mantha was told from day 1 with the Wings organization what they want him to work on. With that they tell players they want them to be dominant players at whatever step of development they are on. He certainly deserves high marks for that, but his defense is better and his compete level is better. Are they all the way there, of course not, but he is going to log big minutes the rest of this season and likely next year in the AHL. He will be brought along to succeed and tweaked on rather than overwhelmed. Sure you can throw kids in the deep end of the pool, some are built for that, it just isn't the way the Wings approach development.
When they think a kid is ready for it they have typically allowed him playoff time in limited minutes or quick tastes of the NHL to gauge where they are and allowing them to see the NHL game and strengthen again in the AHL. It is a different system and quite frankly the luxury of doing it seems to be waning and we will see just how long they can keep doing this. Both Jurco and Ouellet were getting their taste of NHL life before 21 this year, so they seem to be heading towards bloodying these guys in the NHL a little earlier because the failure of vets in the organization. That is good news for Mantha, if he grabs his AHL opportunity by the throat, he has an excellent chance of making it to the NHL quicker than some of the past Wings depending on the off-season.
