GWS still have a 10% COLA I believe, PLUS, a much bigger salary cap than all the other clubs, as part of their start-up concessions. On top of COLA, they have an extra 1 million $ in their salary cap this year, an extra $880K next year, $760K in 2016, $640 in 2017 and an extra $520K in 2018, which would be why they haven't lost too many from their list so far and have so many signed up until the end of 2015, in spite of the fact many of them could be playing more if they were at other clubs right now. They can just keep on paying them huge piles of money for quite a while to come.
