Williams has been a consistent defensive presence across his five U20 Championship appearances, averaging close to six tackles per match and peaking at ten in a single outing — numbers that point to a lock who prioritises physicality and contest. His carrying is steady rather than explosive, contributing reliable metres per match and demonstrating a willingness to carry the ball into contact in tight channels. The balance between his tackle and carry counts suggests a player who sees his primary value in the defensive and set-piece aspects of the lock role.
