Logan was a member of the Chelsea side that reached the 1915 FA Cup Final. He was one of the few Chelsea players to get a positive mention in the Manchester Guardian report on the final for a few "dashing excursions" into the Sheffield half, he failed to score. By then, he was judged to be "an ideal centre half who showed judgement in his play", although in his early years he had been considered a forward and had a good scoring ratio for Falkirk. He was playing further back when capped by Scotland.
