I agree with everybody who said Iowa. Iowa has taken people nobody else offered(Gallery, Greenway, Bob Sanders, etc.) and taken walk-ons (Dallas Clark, Consodine, Nelson) and turned them into draft picks. Iowa seems to have a real knack for talent that I wish Notre Dame had. I think their recruiting strategy is to only recruit people with an outstanding work ethic. It seems to be working for them.
I seriously think that ND should start taking more walk-ons.
