Plans and a players future can always change depending how a player reacts to such a situation and Hancock is proof of that, Barba is his own man and if he felt he could do better elsewhere after the news then that's his choice, but I have little doubt if Barba knuckled down, looked to really address his issues on and off he could have changed the situation for him and even if it didn't, he would be better placed then he currently is.
Do you honestly think he had a chance at either fullback or five-eighth, the only two positions he is capable of playing?
Bennett very early on signalled his intentions of playing Boyd at fullback and Milford at five-eighth. There's no two ways about it. Barba is (or at least used to be) too good a player to be playing rubbish minutes or in ISC. He is a former Dally M medalist, and he is at an age when most players are at their peak. I doubt he'd want to be wasting whatever years he has left in the game, when he should be at the peak of his powers.
Of course it will take some time before Barba reaches anything remotely close to his best again, but that's not to say he cant regain those heights.
The saddest part of all this is that one of the worst decision Barba ever made was to come to the Broncos. He's career has taken a massive nosedive since and it's really unfortunate. I doubt this would of happened had he stayed under the guidance of Des Hasler.
