Should Wallace have a go at coaching from the boundary for a while a la what Sheeds has done the past few weeks?
There would still be plenty of experience in the box with Royal, Wheadon, Gordon Casey and David King while Wallace could directly instruct the players particularly the young guys coming on and off the ground what he wants from them face to face. Plus you wouldn't want to disobey the team rules if you knew Terry could immediately call you over for a "chat".
