From what I read on this forum, AD delayed negotiations until after the WC. That is his decision, but it does expose him to WTs moving in another direction eg Moses. In any event, Moses is a quality half regardless of feelings towards him. If he were to come back to WTs, I would be very pleased.
We rarely agree on players but I do in regard to Moses.
He is a better player than what we have. I question his ability to be the man to steer a team to the premiership but he will make us a top 8 side. If he regularly takes us into the 8, there's a knock on effect to being attractive to other potential recruits.
I don't like him but I think a utilitarian approach is required with him. Bring him back, use him as long as we need him and then move on.
