I actually agree with you even though its partially against my argument. I don't think anyone is doubting that you need high ranking recruits though. I personally feel that if you look at the nations top 10 every yr you may not find a top 10 recruiting class in all of them but what you will find is a great coach and established culture.
You are right. It takes both because good recruiting with no development ends up with a fired coach. Good development with less than good recruiting usually means the coach gets hired at a better school. Good recruiting AND good development means you are in the mix for championships more often than not.
