This isn't even arguable. The Central division is the best divison in the NHL. All five teams in the division are in the top 8 of the Western Conference. All are within three points of each other. Chicago has 15 points in 14 games, St. Louis has 14 points in 9 games, Detroit has 13 points in 9 games, Nashville has 13 points in 10 games, and Columbus has 12 points in 10 games. As of right now, this division is wide open.
Chicago- They're currently on top of the division but have also played at least four more games than any other team in the division. Look for them to fall back into third pretty soon.
St. Louis- In my opinion, St. Louis has been the most impressive team in the division so far this season. They don't have anybody that really scares you offensively, but Jaroslav Halak has been unreal so far this season. The Blues are not going to be as bad as people thought they might be but I don't expect them to hang around in 2nd place either.
Detroit- What can I say? I hate them but it looks like the Red Wings are for real again. They're playing well right now and they've still got as good of a first two lines as any team in the league.
Nashville- This team has got to get healthy. There's no way to know how good this team can be yet. Once healthy, I expect that they can be excellent. They've just all got to get healthy and stay healthy so we can see. Drink some milk.
Columbus- The Jackets have had a decent start to this year but I wouldn't expect it to continue down the road. They just simply don't have enough to make a playoff run. Expect them to be a bottom three team in the Conference here shortly.
The question is: Who is going to come out of the Central division and when they do, are they going to have anything left? Teams are going to keep beating each other up in this division. It's very similar to the SEC in college football. It's the best conference in America and whoever comes out is usually the best team in the nation. Likewise, whoever comes out on top as the Central divsion could be looking at some serious success come postseason time. Right now, it's anybody's game.
