According to John Nyren, Minshull was a "capital hitter, and a sure guard of his wicket" but "not an elegant player, his position and general style were both awkward and uncouth".
Minshull evidently had a high opinion of his own ability and was said to have been "as conceited as a wagtail and from his constantly aping what he had no pretensions to, was, on that account only, not estimated according to the price at which he had rated his own merits".
Nyren added a physical description: "a thick-set man, about 5'9" in height, rather a slow mover in the field (and had) a tendency towards injury and illness".
[1] Little is known about him personally except that he was for a time employed by the Duke of Dorset as a gardener at Knole House, near Sevenoaks.
[2] Minshull's century was scored on Thursday 31 August 1769 when he played for the Duke of Dorset's XI against Wrotham.
