My thoughts are that good defenses require better athletes than good offenses. In other words, you can turn around an offense on coaching, but it takes recruiting to turn around a defense.
I don't have a lot of data, but it seems that most of the turnarounds for BCS teams that are not historically recruiting hotbeds came on the offensive side of the ball. Stanford (although they had a great D), K-State, Okie State, A&M.
I'm kind of struggling with this because it seems the coaching talent pool this cycle is deeper on the defensive side of the ball.
