I hope Walker stays but let's play him at centre if he does. Jakes role has been questioned in this thread, but it's mostly been because of how his role has been impacted by Walker coming on to play lock. Obviously that means we have an additional small, ball playing forward on at the same time as Jake, and we are short a prop in the middle. Walker as a centre, means we can simultaneously resolve this issue, and improve our centres. Let Jake play the role he has always played for us, and Walker the position that he was arguably born to play.
