Most of the major schools don't have a need to strengthen their schedule because they have SEC teams or Big Ten teams or whatever on their schedule already. If an Alabama or Penn State or Miami needs to improve their schedule, it's more prestigious to play another major program in a major conference rather than Boise. It shouldn't be, but it is because there's still more name recognition with USC/Ohio State/etc than there is with Boise, but the game is just as tough. If Boise wants widespread respect and a chance to play for a BCS title, they can't play 1-2 BCS programs and then Western Michigan and Tulsa every year. Especially not with how awful the WAC is. To be able to get into the BCS title game, they'll pretty much have to face major programs in major conferences. Voters aren't going to give them a ton more credit for beating Western Michigan instead of Toledo (though they should) and the coaches' poll is a huge part of the BCS. TCU, BYU, Utah, etc. would help, but it'd be just like last year's Fiesta Bowl – voters and many fans would write off the win as just two overhyped "minor" programs beating up on each other. To have a chance to crack the BCS title game, Boise has to play and beat the elite programs or move into the Pac-10, Big 12, etc. If their concern was simply to finish undefeated every year, they'd schedule Toledo/Wyoming/1AA/Arkansas St every year and not be trying as hard as they reportedly are to play the top teams out there. If it's true that they offered to play one-time deals with elite programs, that tells me their interest is garnering enough national attention to reach the BCS title game, not simply to go unbeaten.
