Rankings in the NHL

I have decided to try ranking NHL teams by using the Elo Rating System. It is a system that is very common in giving a rating to individuals competing in 2-person events like chess. I tried it with football a few years back, but it wasn't as successful as I was hoping since football has so few games per season. I figure the NHL plays enough games to get a good statistical sampling to more accurately rate teams.

I did use a variation of the Elo system though. All teams started the year at a score of 200 points. The K-Value I used is the traditional 32 points(for teams under 2100). The change I made though is that if a team loses in an overtime situation, they do not lose points for that game while the winning team still earns points.

So far, for the games up through 10/19/2011, here are my rankings:

Top 5
1. Washington (287.79)
2. Colorado (259.89)
3. Detroit (259.73)
4. Toronto (257.26)
5. Dallas (253.30)

Bottom 5
1. Columbus (129.40)
2. Ottawa (147.99)
3. Tampa Bay (168.18)
4. San Jose (168.88)
5. Montreal (169.44)
