The Bulls have fallen far from the lofty heights of 2007-10, when they won three titles.
They were smashed in the scrums, and seemed clueless on attack and fractured on defence. Why they persisted in kicking good ball away to a strong counter-attacker such as fullback David Havili, who scored a try off one such skewed clearance, was mystifying in the extreme.
The Bulls did score three consolation second spell tries, but their Loftus citadel is no longer a fearsome venue for visiting New Zealand teams.
"The walls of the fortress came tumbling down," quipped TV commentator and former Springbok Joel Stransky.
Todd was ecstatic that the Crusaders had won at Loftus for the first time since 2008.
"It was good to get a win here, of all places. The boys were up for it and fed off that early momentum," said the opensider.
The Crusaders will host the Hurricanes next Saturday in a game most New Zealand fans will relish, while the Bulls will have to deal with the Highlanders in Pretoria.
