Thomson, the Otago loose forward, was named at No 8 to take on the French tomorrow night in Auckland, after starting on the openside flank against the Japanese last week.
Thomson will have to use his running game more off the back, something which has slowly developed in the past couple of seasons.
He was a master at the turnover when he first made a name for himself in the national side, and said yesterday that role may coming back into vogue.
"I think this World Cup has shown players who can get on the ball legally . . . that there is a bit of a shift back towards those players now. The referees tend to have been giving a bit more latitude to those fetchers,'' he said.
"I have seen quite a lot of success for those players to get on the ball and get penalties. I think it is starting to swing back that way which is good.''
