In order of priority I'd hope we were looking for a halfback, a prop forward and a front row/loose.
I'm actually ok with the backs we have and I think if Grant and Gibson leave then players from our academy can step up.
The foundations of a good side are built in the pack and the halves. The backs are essentially luxuries and I wouldn't want us to be using too much of our budget in that area. You could argue that whilst Webster has been very good for us and very consistent, we're still not getting our money's worth because our play is so poor that he never gets the ball in a position where he can do damage with it.
