One of his major power moves was the founding of the Coach of the Year Clinics, now sponsored by Nike, with University of Oklahoma coach Bud Wilkinson. The clinics traveled nationwide to provide training and development tools and networking opportunities for high school coaches. When the clinics traveled to the South, the Black coaches couldn’t attend workshops with the white coaches, so Duffy’s coaching staff, including defensive coaches Henry “Hank” Bullough and Vince Carillot, would lecture in separate rooms and sometimes in alternate venues to accommodate Black coaches.
