He coached at Pearl High School until 1984 after which he transferred to Maplewood High School, remaining there until the coaching position at Whites Creek High School became open in 1986. He finished his career there in 1991.

His success on and off the court can be measured using the high esteem with which Coach Ridley is still held. He won 684 games and lost 171. His wins included 15 District Championships, eight Regional Championships and five State Championships. His teams competed in six other state tournaments. His record is very impressive, however, his legacy is still passed on by many others who were influenced by him in his other roles of teacher, mentor, friend and family member.

Coach Ridley, known for his love of people, is remembered for using his leadership and influence to begin the process of integrating high school athletics in 1965. The city and state were made better through his efforts. His team won the first integrated State Championship in 1966, and in 1991, his team at Whites Creek was ranked number one in the nation for part of the season.

Coach Ridley received many awards and recognitions through the years. In 1991 Ridley was inducted into the TSSAA Hall of Fame. He was also honored by the Nashville Sports Council being given the Lifetime Achievement Award in 2002.

To quote Coach Ridley, "...If you work kids at doing things the way they ought to be done and treat them fairly, you're going to do all right. When they're through and they come back and can look at you and respect you, then you've had the proper relationship with them. When they know you've been fair, they can't expect any more. That's the best any man can offer."
