The hooker: The tip of the spear of any successful pack.
The man brave or mad enough to surrender himself to the support of the two hulking slabs of beef either side of him, whose job it is to keep his scrum up while he swings at the ball.
He’s then got to reinsert his shoulders to their sockets and throw the ball in at the line-out with dead-eyed accuracy and, while he’s at it, rampage all over the park as an extra attacking weapon.
Plenty have passed into rugby legend from the No. 2 shirt; these are my top six.
