This is a very interesting thread. Clearly the results support the premise that the Roosters and the Storm are by far the best managed clubs in the completion.
When you break the numbers down into premierships and finals appearance, the results further indicate that being one of the junior development clubs is a clear disadvantage. Of the true development clubs, Dragons, Eels, Knights, Panthers, Wests and Warriors, the Dragons are possibly the best performing. I do not consider the Broncos a junior development club because in Brisbane, development is left to the second tire completion clubs.
Following are the number of premierships won by each club and the number of times that each club has made the playoffs since 2001 (excludes premierships taken off the Storm):
Broncos: 1 17
Bulldogs: 1 12
Cowboys: 1 10
Dragons: 1 11
Eels: 0 9
Knights: 1 8
Panthers: 1 8
Souths: 1 8
Raiders: 0 10
Roosters: 4 14
Sea Eagles: 2 11
Sharks: 1 12
Storm: 2 17
Wests: 1 3
Titans: 0 3
Warriors: 0 8
As was mentioned by another member, the NRL needs to introduce a scheme to reward the development clubs for the management of their of their juniors and to ensure the longevity of the game.
