The Boise State analogy is pretty good (although I think the ECAC is relatively better then the WAC, but the basic point is fair). This if course gives Yale a very small margin for error... they have to have a very gaudy record to have serious consideration as number one, just as Boise State has to go undefeated to have a chance. And even that doesn't necessarily work if you're not impressive enough... just ask TCU. As long as they stay recognized as one of the top 8, though, they'll have as good a chance in the playoffs as anybody, which is all that really matters.
The big worry for me is to find out how they do against a talented physical team. As a pretty nonphysical team, they have no problem skating rings around untalented physical teams, ant they are probably the fastest team in the country. But when you don't play the best teams on a consistent basis, what you gain in record you lose in experience against styles that you aren't really ready for. That's why the win in the playoffs against **NORTH** Dakota last year was so impressive, even though they couldn't close the deal the next day against BC, even though they scored 7. To me, it's not where they're rated... if they don't have a bunch of injuries they're going to be rated high enough. It's an experience question to me.
