[McConnell was] a strong, dashing defender. He was well known as close playing spoiler with good spring and unexpected speed in his long legs. Surprisingly, he had a vision range of not much more than fifty yards, but this never affected his play. He had a remarkable ability for such a big man and was a top full back and centre half back during his career. He was a member of the 1949 and 1950 premiership teams and burst into League prominence by beating Carlton star, Jack Howell, in the 1949 grand final.[3]
McConnell retired, controversially, at the end of the 1956 season.
Vice-Captain of the senior team, and its regular full-back, McConnell was selected as its 20th man in the last match of the season, against Geelong.[4]
"He withdrew from the team [announcing his immediate retirement on the Friday] claiming that his form warranted a place in the eighteen. 'I have no grudge against Essendon, but I consider that I could have had a better go this season', he said."[5]
The first emergency, John Towner, was appointed 20th man for the match.
McConnell served on the Essendon Football Club's Committee (1957-1965), was its secretary (1973-1979), following the retirement of Bill Cookson, and was its first general manager (1980).[6][7]
