Coach Eddie Jones on Thursday said the Wallabies are "remodelling" with young players, believing youthful vigour can halt a slump with just five weeks to go until the Rugby World Cup.Under mounting pressure after losing his first three games in charge, Jones said it was obvious that change was needed and did not rule out the possibility of McDermott leading the Wallabies at the World Cup, having initially named James Slipper and the currently-injured Michael Hooper as co-captains.
