Hi Pal,
In respect to Hill there is no written rule on when to call a potential candidate or player manager. ( timeframe)
In fact being too keen,generally means more $$ to the other party.
The fact he took his time,a more measured approach and called when he felt was right was probably a good move, made them sweat a little particularly if they were expecting the phone call.
It would be good to see the current mob demonstrate the reasoning behind a new ceo, albeit a low profile one,makes no sense.
