Longtime Boyd football coach and athletic director J.G. Cartwright announced Monday after a meeting with his players that he will be retiring at the end of the school year. Cartwright, who has been the Yellowjackets’ football coach for the past 35 years, said he turned in his paper work Friday, but wanted to wait until after he talked with athletes Monday before making the announcement. “Everyone I started out with has been retired several years,” Cartwright said. “It’s time I try to do something else.” Cartwright compiled a 274-122-5 record between 1977 and 2011. He guided the Yellowjackets to a pair of state championships in 1983 and 2004.
