Of the 17 who won the GF last year, 6 came right through the Panthers system from a young age, including Nathan Cleary who came with his father aged 13, another 6 were scouted from country/NZ/Pacific islands as teenagers and provided accommodation, Kikau was signed from the Cowboys who had put 2 years into him, and subsequently we put another 2 years into him, and the remaining 4 were signed as more or less established first graders who had debuted elsewhere but were looking for an opportunity. None of the last group (Koroisau, Momirovski, Capewell and Sorensen) were big money signings (Koroisau in the $500k region), all of them made significant career progress in our system so it could be argued even the imports were to some degree developed into better players by us. All of them are worth more now than they were bought for, and 3 of the 4 have taken advantage of this by signing elsewhere.
What the Roosters/Storm do is more slanted towards the second group and certainly the third, since they have very few (Roosters) or no (Storm) juniors in their own area of domicile. The above grants breakup certainly wouldn't be equitable, and with Panthers having won 89% of matches in the past two and a bit seasons, there is not a chance the NRL are going to alter the balance in our favour at this point in time. But they do need to find a way of getting all clubs to pull their weight in player development, which isn't happening now. The Roosters and Storm are not the problem in this regard. The problem clubs can mostly be found near the bottom of the table.
