Here's my effort.
8.5 -
5.0 - Melbourne, West Coast
4.5 - Essendon
4.0 - Fremantle
1) Geelong
2) Hawthorn, Bulldogs
3) Port, St. Kilda
4) Brisbane, Carlton, Richmond
5) Sydney, Adelaide, Collingwood, North Melbourne
6) Essendon, West Coast
7) Fremantle, Melbourne
Each line = new bracket of quality. First listed = best in each bracket, last worst.
I expect Carlton and Richmond to move into bracket 2 by end of 2010 however, with Bulldogs entering bracket 1.
