The back line needs to sorted out and whoever are the first choices these lads given an extended run together.
Wing / centre is a lot to do with partnership and understanding, no wonder they don't hit the straps all the time when it constantly changes.
I wonder how much game time Potts, Tyrer, Cowling and Fox ( if they are the ones ) will play for Fax together to have a chance to make it work.
If I were a centre and had not been given a real chance and found a second row playing in my position I would be less than happy.
