Ron, the way it looks, with many coaches dropping back to D2, the power conferences may be the only ones left in D1 with human coaches.
It's certainly a bit easier to recruit from a power conference, given the extra money, better prestige, etc., but if you're happy where you're at, there's nothing wrong with staying at a smaller school. Probably a bit more challenging, sure, but when you succeed it makes it all the sweeter. And in all honesty, sometimes trying to recruit at a bottom feeder BCS school is actually harder than recruiting at a smaller school (for instance, the big boys always seem to want to take all the good players. Can't imagine why really. But, you kind of get into a bit of a rut trying to compete against teams full of studs when you're bringing in role-type players, if that makes sense. It'll definitely make you have to learn how to coach though)!
Guess it really comes down to what your goals are.
