Across 27 matches, Ducat has established himself as a high-volume defensive presence, averaging over five tackles per game and accumulating nearly 150 tackles in total — a workload that speaks to consistent, reliable involvement at the breakdown and in the tight channels. His carrying is steady rather than explosive, contributing short-range metres at a lock's typically functional rate, with his best outings showing he can step up both his physical presence and ball-carrying when the game demands it.
