I was surprised to see Boise stay behind Oregon. TCU isn't in quite the same position as BSU since the MWC is considered a stronger conference than the WAC. This year is proving to be different, but historically, the WAC is a creampuff conference. Being from the Dallas area helps TCU in a small way as well. When people around the country think about football they think of Texas long before they think of Idaho...lol
All the national attention that BSU has gotten this year has probably been the difference. The WAC has done very well with it's OOC play and moved to within a 1 point of the ACC in strength of schedule. Things seem to be falling just right this season for the Broncos so we will see what the year brings, but the preliminary BCS polls has them on top, their WAC schedule doesn't look to hurt them as bad as once thought and as long as Oregon drops one, they could be in contention for the NCG as long as they win out.
