Brown has only been a good player whilst Moses is on the field, and has shown he is borderline dreadful when Moses is off the field.
What's to say that someone else, on a third of what Brown is currently on, wouldn't become as good playing with Moses?
With no Gutherson to lead him around any more, I suspect Brown is only going to show what he showed yesterday with Moses not on the field.
He's not worth what we're paying, nor what we intend to pay him in the future... Let him become the Knights problem.
