Fascinating article: http://www.dailytelegraph.com.au/ne...igning-rabbitohs/story-fngr8ice-1227258515619 Over the last 10 years the Roosters have a penalty differential of -297. They have not finished with a season with a positive penalty differential in 10 years. Over the same period, Souths have a +153 differential! Souths have had a positive penalty differential for eight consecutive seasons. Certainly makes them hard to beat. The Roosters just can't buy a penalty.
