From 2001 Deans concentrated solely on the Crusaders. The 2001 Super 12 season was his least successful in charge – the Crusaders finish tenth. But the following season, the Crusaders went through the entire season undefeated and won their fourth title overall, and their second with Deans as coach. In the following two seasons the Crusaders finished runners-up to the Blues in 2003, and then the Brumbies in 2004. The Crusaders won their third title under Deans in 2005. The Crusaders won their sixth title (the first of the expanded Super 14) in 2006, and their fourth win with Deans in charge, making him the most successful coach in Super Rugby history so far. In 2008, Deans' last season in charge of the Crusaders, he coached them to a seventh super rugby title after they beat the NSW Waratahs at Jade Stadium. In honour of the Deans family, Jade Stadium (now AMI Stadium) erected a new stand called the "Deans Stand". Following 22 February earthquake, there remains doubt as to whether AMI Stadium will ever be used again, after some of the ground, including parts of the Deans stand, suffered structural damage. As a result, the new stand was not showcased during the 2011 Rugby World Cup.
