The smaller/weaker interstate clubs will be most at risk with this new mode for player movement. Most players originate from Melbourne and if they are not getting a regular game at their club they will use Free agency to go back home particularly to one of the bigger Victorian clubs. Interestingly no one has gone near the Doggies. This suggests to me either that they are well prepared for the period or have not players of interest that can be exploited with the Free Agency rules.
I'm hoping this also paves the way for a more exciting Trade Period too with less 'big name deals' holding back genuine player movement.
