It's just not true that schools in conferences that are not "BCS Automatics" try to "duck" schools that are in those conferences. It's kind of hilarious to hear the heavy dose of hypocrisy that an Ohio St. doesn't have the flexibility to schedule some school because they have to play their conference schedule but that TCU is "ducking good teams" with total disregard that they also play in a conference and have a conference schedule.
It's a fact that teams like South Florida, East Carolina, Fresno, Boise, etc. have pursued trying to schedule teams from the automatic conferences in the past. But, there are always the "scheduling issues" and many of the so-called "elite programs" in the automatic conferences simply don't want the headache of scheduling a school that will give them problems on the field, there just isn't any good incentive to schedule a solid team from a "minor conference" that could knock you out of a major bowl and the Big Money. The "ducking" comes from the other side -- those that have everything to lose and nothing to gain.
Simply put: Ohio St. would rather play Youngstown.
