Another factor was the bizarre scene of the visitors playing the final six minutes with only 14 players on the field because they had used up all their reserves. Mitch Hunt replaced Richie Mo'unga at first-five but suffered an injury most assumed was a head knock which would have allowed Mo'unga to come back on. However, the officials decided otherwise and off Mo'unga went again.
Still, the Crusaders went to the top of the Super Rugby table – possibly briefly – and the defending champions remain the team to beat. They were slightly off their game tonight but not too far off and going by the form book they should provide the Chiefs a lot of problems in Christchurch next weekend.
It was vision and skill execution which had the Crusaders 10-0 up in the first 10 minutes, with Jack Goodhue laying on a try for Braydon Ennor with a cross-kick and, straight from the re-start, Will Jordon and Ennor combining for Jordan to score his first try for the franchise.
And while they stretched and pushed the Reds defence which appeared to fatigue the home side, the Crusaders couldn't get across the line again until the second half when they went back to basics with lineout drives which reaped tries for Whetu Douglas and Jordan Taufua.
The visitors' relative battles were were probably due to the defensive effort and willingness for the Reds - hindered by an early injury to highly-regarded 19-year-old centre Jordan Petaia - to work for each other under Brad Thorn, but a lot of it was simply down to poor skills from the Crusaders.
It seemed they had too much possession at times and didn't quite know what to do with it. Whereas earlier they had found space near the sidelines, in the second quarter they went to width too quickly and were flat and static as a result.
Samu Kerevi's converted try was a good reward for the Reds' stubbornness, and while flanker Liam Wright's try was ruled out for obstruction, Higginbotham caught the Crusaders short on the blindside to narrow the gap and deny the Crusaders another point.
