This.I don't think we have the big line bending forwards to play through the middle, our backline is our strength and spreading to the edges quickly is working so there's no reason to change it. Teams might be onto us but there's not much they can do as long as we play faster than them and that's what we're doing. BA has picked a style that suits the players we have and even though we're still a bit weak up the middle we're winning games so credit to him for getting the side playing well despite our weaknesses.
It's all well and good that the opposition might know the ball will spread across the backline.
It's another thing altogether to be able to stop it
