As I explained above, making race a proxy for recruiting prowess, is how you inflate the ability of lesser qualified coaches. It's wishful thinking that is tilting at windmills. Ty was a terrible recruiter. Corwin Brown seemed to be an okay recruiter but he wasn't prepared to actually coordinate a defense. That hire doomed Weis's career.
You hire ability to win based on demonstrated ability to win. Especially at ND when bad seasons still generally pull in top 10 classes.
