Lawrence is an outstanding Centre who keeps getting better. So, fingers crossed he stays as a Centre. Remember Sheens saying "his long term position is 5/8". Let's hope that the Benji 7 / Lawrence 6 idea has been put to bed (and shot, buried and covered with cement).
Chris was a real "heavy bump and hope they go down and then wrap them up on the ground" sort of tackler early on (but no one noticed in his debut games because he was scoring 3 90 metre tries per game!). But, he has really improved. It feels like his attack has been stymied a little while his defence improved but I think that'll change once he gets his mojo back.
