Tracey Nelson crunches the numbers and looks at history ahead of this week's Super 15 clashes.
CHIEFS v FORCE (Pukekohe, Referee Mike Fraser)
The Chiefs have won five of the six games played between these two, with the Force's only win (by just one point) coming in 2008.
The Chiefs have scored the most tries (35) and made the most offloads (135) of any team in the competition. They are also the second best team for clean line breaks, with a total of 101.
The Force have scored the least tries of any team, with just 17. They have only made 45 clean line breaks.
Gareth Anscombe moves to first-five this week, and remains the competition's top points scorer with 163 points. He has scored five tries and made 13 linebreaks.
One thing the Chiefs and Force have in common is their poor lineout stats, sitting 13th and 15th for percentage won on own throw (80 v 78). Toby Lynn and Hugh McMeniman are the Force's go-to men having taken 33 and 29 takes respectively, while Brodie Retallick has made 28.
Sam Cane has made 148 tackles making him third highest tackler overall, while Liam Messam has made 118.
Overall the Chiefs are averaging more tackles per game (130) than the Force (108) and their percentage of missed tackles is lower (15 v 17).
BLUES v REBELS (Auckland, Referee Garrett Williamson)
It's one game each with the Blues having won the inaugural game in Auckland in 2011, but having lost 23-34 in Melbourne last year.
The Blues are the 3rd best team for linebreaks with 81, while the Rebels have made 58. Charles Piutau is the top line-breaker in Super Rugby 2013, having made 16 to date.
Piutau has made the most runs with the ball for the Blues with a total of 92, but is closely followed by Luke Braid who has made 89.
The Rebels' lineout (84.6 percent) is running slightly better than the Blues (82.5 percent), and last week they won 100 percent of their throws against the Chiefs. Scott Higginbotham has taken 35 lineouts this season, making him the fifth ranked lineout jumper.
The Blues have a 87.9 percent success rate with their tackles, despite missing 25 against the Stormers last week. The Rebels are just slightly below that with an 86.7 percent success rate.
The Rebels made just five handling errors last week, compared with the 15 made by the Blues.
The Rebels have conceded the most yellow cards of any team, with a total of six.
CHEETAHS v HURRICANES (Bloemfontein, Referee Stuart Berry)
It's close in these encounters, with the Hurricanes on four wins and the Cheetahs on three. The last time these two sides met was in Wellington last year, when the Cheetahs got up to win a high scoring game 47-38.
High scoring games have been a trend when these two sides meet, with the Hurricanes winning 50-47 the last time they played in Bloemfontein in 2011. Overall the Hurricanes score an average of 32.7 points and the Cheetahs 26.6 when they play.
Despite the Hurricanes having scored one more try than the Cheetahs (24 v 23) they have only won five from 10 games, while the Cheetahs have won seven of their 10 matches this season.
The Cheetahs have made 69 clean line breaks and 72 offloads so far, while the Hurricanes have made 64 line breaks and 90 offloads.
The Cheetahs have the second best lineout behind the Bulls having won 87.9 percent of their throws, while the Hurricanes have won 83.8 percent of theirs.
The Hurricanes will need to keep a close eye on the Cheetahs as they have made 14 quick throw-ins this season, meaning 11 percent of their lineouts have been un-opposed quick throws.
Raymond Rhule (five) and Willie Le Roux (four) are the top try scorers for the Cheetahs, while Julian Savea and TJ Perenara are top equal for the Hurricanes with four each.
KINGS v HIGHLANDERS (Port Elizabeth, Referee Jason Jaftha)
It is the first time these two sides have met, with the Highlanders coming into the game on the back of their first win this season while the Kings conceded a whopping 11 tries in their defeat by the Waratahs last weekend.
Hosea Gear and Ben Smith have both made 11 linebreaks this season, with Gear having beaten 35 defenders and Smith 34. Smith is also the fourth best offloader in the competition with a total of 18.
Wimpie van der Walt (147) and Andries Strauss (116) have been the Kings' top tacklers, and have been instrumental in seeing the Kings in top spot for tackling success percentage with a total of 89.8 percent.
The Highlanders are the better team when it comes to winning their ruck ball with a 95 percent success rate, while the Kings have a 93 percent success rate (worst equal with the Cheetahs in the competition).
The Highlanders have struggled with their lineout this season (second worst) and are currently running at 79 percent on their own throw, while the Kings are at 85.4 percent.
John Hardie has struggled to stand out in a losing side, but has made 124 tackles and 78 runs with the ball this season.
The Kings' goal kicking first-five Demetri Catrakilis is just seven points short of 100 points for the season. The top points scorer for the Highlanders is Colin Slade with 55.
