I think the idea of having a much greater oppurtunity of an east-west championship is cool. Even if they do the seeding and bracketing the same, allow for the changing of semi-final games to promote an east-west final.
My Frozen Four scenarios:
2008 Frozen Four
North Dakota v. Michigan
Boston College v. Notre Dame
2007 Frozen Four
North Dakota v. Michigan State
BC v. Maine
2006 Frozen Four
North Dakota v. Wisconsin
BC v. Maine
Yes, the possibility of playing a regular opponent first is greater, but wouldn't you rather play them first than for the title?
