Agreed. They've actually told teams that they'll go to their place and play them so they don't even have to go out to Bronco Stadium. Most teams are just too scared or have too much to lose with a loss and respect that Boise State would have a very good chance of beating them. In a system where 1 loss usually means "kiss your title chances goodbye," why risk it?
Either way, the national championship in the first year of my dynasty was actually Boise vs. TCU. I can't remember who won, but I couldn't help but think that even if they were the only two undefeated teams left in the nation, they still wouldn't both be in the title. Not much of a "BCS" championship if there are no BCS teams playing.
