CHIEFS v CRUSADERS (20-17)
A high error rate by the Crusaders was the difference in this match, with the Crusaders making thirteen handling errors while the Chiefs only made five. Richie McCaw was a main culprit with the hands, knocking the ball on three times.
The Crusaders missed 30 tackles to the Chiefs' 14, with the normally reliable Sam Whitelock and Dan Carter both missing three.
Dan Carter's missed touch finder was the fourth time in three games he hasn't managed to put the ball over the sideline from a penalty.
The Chiefs conceded 13 penalties in this match, while the Crusaders conceded 10. Tawera Kerr-Barlow and Robbie Fruean were the most penalised players on the field with three each.
Despite the return of Craig Clarke this week the Chiefs still only won 60 percent of their lineout throws, losing two to overthrows, a penalty conceded for pushing, and one stolen by Richie McCaw.
Clarke was the Chiefs' main source of lineout ball winning all four of his throws.
The Crusaders did win five breakdown turnovers to the Chiefs' four, but were also penalised for not releasing the ball when tackled on three occasions.
Aaron Cruden became the top points scorer in Super Rugby 2012, with his two penalties and two conversions taking him to 234 points to date.
Dan Carter's third penalty goal of the night brought up his 100 points for the season, his fourth penalty shot of the game leaving him on 105 points in total for 2012.
