I believe only one small-conference team is guaranteed a bid. I remember this discussion going on when BSU was undefeated last year (which seems like eons ago, being that we're 0-7, but anyway) and that's the way I think it goes. ND is factored in with the big boys so them getting in wouldn't keep both TCU and Boise out, but I believe only one of them can get in automatically. Boise was eligible last year I believe but since Utah was already in, Boise was not taken.
