I would say it actually does for a while. The NA game is different, and the AHL is better than the league he was playing in before. He can get used to better competition and get used to a different style of game while getting 18-19 minutes a game instead of being a scratch. NHL teams don't practice as much as they used to during the season, and many of them are glorified walkthroughs. Now for how long is relative for each player. Maybe the lights up the next 15 games in the AHL and basically proves that he can handle this... maybe the effort dies down as he isn't trying to prove himself so much (if that happens, he will have struggles getting a call up again)... hard to say. I will agree Everberg is at the age where he shouldn't need much seasoning though, just some time to get used to the NA game and fix some bad habits he could get away with in Sweden. That might take 10 games, it might take a full season. After that, he will be about as good as he will ever be. So right now, if the choice is scratch or AHL... without a doubt AHL.
I think I would definitely agree with you, and side with this line of thinking for Everberg, if I hadn't seen him in the pre-season games and five regular season games.
I didn't see any reason to be concerned that he doesn't get the NA game. He can play the NA game better than anyone on the 4th line for sure. I think his game is much more suited to the NA style than in Sweden anyway. He keeps it simple, and has a very meat and potatoes approach. Forechecks hard, goes to the net hard, back checks hard, is in the right position in all three zones. He gets it.
Also in terms of NHL practices, they may not be on the ice as much as they used to, but they still have video session on their off days. With Roy's attention to details in both team and individual play, any improvements he may or may not need to make will be benefited by this.
Edit: Screw middle ground.
In all reality, I think your previous post was the middle ground. We all think Everberg could help the team as it is now, but disagree on Cliche's PK effectiveness, and how much Lake Erie will help Everberg's game.
