In some games he only played last 10 mins bro, but not on his debut. Like you said, he played a full game in the centers against Parra. In that game and in round 2 against Cronulla, he was filling in for Matthew Utai, who was suspended. Willie Tonga was our other center, but after Matthew Utai returned from suspension and Ben Harris recovered from injury, SBW was used as an interchange back rower.
In 2004, his debut season at age 18/19 he started in 2 games and played in 13 games as interchange. That year Roy Asotasi was the big minutes interchange, Cory Hughes and Reni Maitua were both injected into various positions off the bench, whilst SBW shared the interchange with Jamie Feeney and Dennis Scott.
In 2005, he only started in 3 games and played in 2 games as interchange because of a severe knee and minor shoulder injuries.
In 2006 he started in 15 games and played in 6 games as 'big minutes impact' interchange.
From 2007 to 2008 he started in all 32 games.
