For years doogs had a defensive style that worked for him, which was basically to mark his opposite number and smash the fool if he got the ball, and he was forever in the face of his opposite number.
It worked fine for him for club, state and country - but suddenly Smith wanted him to work in with a defensive pattern and to wrestle rather than smash.
Last year he often got caught up in his old pattern and jumped out of the line, but he was doing it too late because he was trying to stay in line till his instincts took over - he was niether getting up in their face nor keeping a defensive line - he was getting caught in no mans land in the middle.
