Upon his death the Annual Report recorded:-
"Seldom, if ever, has a member devoted himself to, and sacrificed so much for, our club. Commencing as a player, Bill Everson later became a club football administrator, football committee chairman, and from 1946 until this year, guided and advised the Football committee, as football hon. secretary. During those years he deservedly acquired tremendous admiration and respect from all clubs in the rugby unions. The club benefitted considerably as a result of the high esteem in which he was held. His devotion to the club led him to the position of General Hon. Secretary, and this added responsibility he accepted and carried with wholehearted enthusiasm and loyalty."
