If they're not going to make Hartley the new Footy Head then I think it's part of the plan "going forward" that he will be the new List Manager.
When Cameron became GM he was already List Manager and kept both jobs even though he had been bought over by Miller to separate the two jobs.
I have a feeling that Gale at least wants Hartley as List Manager.
This gives us the chance to get IMO the proper structure with a separate List Manager and GM of Footy.
That means Hartley can go forward with the contract renewals while overseeingthe whole List structure as well.
