GREENSBORO, N.C. — North Carolina A&T coach Rod Broadway is retiring after an unbeaten season, ending a 39-year coaching career.

The school announced Broadway’s retirement Monday and promoted assistant Sam Washington to head coach. Washington had served as assistant head coach, defensive coordinator and secondary coach.

The Aggies (12-0) won the Mid-Eastern Athletic Conference title, the Celebration Bowl and the Historically Black Colleges and Universities (HBCU) national championship in 2017.

North Carolina A&T set a school record for wins this season and became the first unbeaten team in MEAC history.

The 62-year-old Broadway went 57-22 with the Aggies and was 125-45 overall, including stints at North Carolina Central (2003-06) and Grambling State (2007-10). He guided all three programs to HBCU national titles, with this season’s crown his second at North Carolina A&T and fourth overall.

Broadway spent seven seasons as the Aggies’ head coach and also won the HBCU national title there in 2015.

Broadway will serve as a special assistant to athletic director Earl M. Hilton III for six months.

“While we are losing one of the greatest coaches of all time, I love that he gets to go out on his own terms, a luxury not afforded to most coaches,” Hilton said. “He took our football program from being the laughingstock of the [FCS] to being the envy of black college football and one of the premier programs on the FCS level. He did it with class and intelligence.”
