It's due almost entirely to the complete lack of real journalists in sports media at all nowadays, thus, no-one has the balls or the know-how to go about asking tough questions and doing some hard work/research.
Personally, I don't think he'll stay on at the end of the year. I think bringing Folkes in is a signal that he has intimated he isn't planning to stay around.
No top grade coach with any nous would hire a relatively successful former head coach as a strength/conditioning coach.
With Sheens being the Test coach, he'll either test the field or, do a meninga and take on the top gig as a part time coaching role/development role thing for the NRL.
He's getting on, he'll be wanting to retire soon anyways.
With Sheens departure, I dare say Simmons wouldn't last much longer. If Folkes becomes Head coach, Simmons will leave. Simmons is like Costello to Sheens' Howard imo, he wants the top gig, but only once his boss goes.
Problem is, a new leader will be elected in and he'll have to retire.
