My personal model
I might be one of the only people who keep Nashville, but i'm gonna piss off another fanbase greatly in doing so.
(Note to fans of this missing team: It's actually nothing against your team at all, as I am a fan of several of your players. This model is actually more based on travel and evening out the West than anything. If you want to make your own models and kick Ottawa to the curb, by all means do so). I will not identify this team outright, but let you figure it out yourselves...
Note: This model would begin in '09 to allow Seattle to build an arena that would be ready as soon as possible.

6 division games/opponent, 4 games/conference team, 1 game/other conference team = 82. Season starts last Saturday in September and ends first Thursday in April, thus hopefully nearly eliminating "June Hockey"
Playoffs: Only top 6 teams/conference (including each of the division leaders) 'clinch' berths, but seeds 7/10 play each other on the Saturday following the final day (7 vs. 10, 8 vs. 9, stats don't count towards regular season) in order to qualify. The brackets are then set up by record as per usual. No more points for OT/SO losses. I know people will hate this idea, but it could be good for potential Cinderella stories.
Why Oklahoma, you ask? Rabid (most times) support of minor hockey teams, and many columnists have called it the next big market in the US. (No links handy, but have definitely read it.) Seattle adds a presence in the PNW. I was actually going to choose Milwaukee/Wisconsin over Winnipeg, but wasn't quite sure as to how well the Admirals had done there going back to the IHL days.
