He is the current DC at USC which is going through a "coaching change." Wilcox is 39 years old and considered one of the best young defensive coaches in the country.
He was Sarks DC at Washington and transformed that defense into one of the best in the country. He followed him down to USC and has done an awesome job with their defense this year. There are reports that new HC Clay Helton plans to shake up the staff.
His loose connection to Michigan would be that both Tim Drevno and John Baxter spent time coaching with him at USC. As I said, very loose connection to our staff but he's a young, by all accounts talented, defensive coordinator with linebacker coaching experience who's currently with a team going through coaching turnover.
