It's one thing to be a great player but quite another to be the greatest player on a team full of great players. And if it's a special thing to be a leader, how much more special is it to be the acknowledged leader on a team packed with leaders?
You can say no more about Shefflin than to observe that he was the undisputed number one on a team which contained half a dozen genuine contenders for the sport's all-time best 15.
