I see what you are saying and there is merit. However is that not what Boxall is on the books for?
To be honest, I thought he was a disaster at fullback last year apart from the first game or two where he had a surprise factor. In the last 5 games teams just waited until he pushed up and inevitably gave the ball away then counter attacked down that side. I am still far from convinced by him I have to say because I've not seen him have a good game at CB
I really do wonder what we expect to be different if we go into the season with the same defence
