The lift in intensity was partly due to the respect the Crusaders have for the defending champion Chiefs, who beat them fairly convincingly in Hamilton in May. The challenge for Blackadder's men will be to step it up from here.
Dave Rennie called the performance by his men "embarrassing", adding they were "outplayed, out-passioned and out-coached".
While they should hold on to their top spot in the New Zealand conference - they need only one competition point against the Blues at Eden Park on Saturday to seal it - the strange collapse in Christchurch has put their top spot overall in serious threat. The Bulls and Brumbies will feel like the Crusaders have done them a huge favour.
The Chiefs simply weren't at the races. They made silly decisions at the breakdown and referee Jonathon White made them pay dearly.
Rennie's men were similarly punished during their two-game tour of South Africa this season - something the coach was worried about - but his side have managed to stay on the right side of the referees since.
It appears their luck has ran out.
Prop Ben Tameifuna was issued with an off-field yellow card for putting his hands on opposite Wyatt Crockett's face and "eye area" during a ruck and the daft behaviour didn't end there.
Sam Cane, not quite on his game in a beaten pack, threw Carter to the ground while offside; fullback Robbie Robinson tried to run the ball from his own line late in the first half only to concede the scrum from which Kieran Read scored his first try; wing Aseali Tikoirotuma coughed up possession too easily.
Blackadder said he didn't feel the Chiefs were quite there mentally, something with which Rennie would wholeheartedly agree.
The only positive Rennie could find from the match was the performance of replacement Andrew Horrell when he joined the action late in the second half. He could have added that lock Brodie Retallick stayed in the fight until the end.
The only negative for Blackadder was the high ankle sprain to lock Luke Romano which is likely to rule him out of the Hurricanes match.
