Traditionally, ruckman have simply been tall players with limited skill and speed, whose only job was to provide a contest in the ruck.

But he had very limited skill in thematic development and even less in contrapuntal combination.

They have no social life outside gaming, and limited skills.

Even so-called 'cleverer' dinosaurs could only acquire limited skills.
