As we move into the closing stages of the regular season (and ever-closer to the Rugby World Cup), our friends at Opta have selected a XV for each conference based upon Super Rugby form.

Players must have featured in at least seven Super Rugby games this year and their selection is based upon their average Opta Index score per game, rather than a total.

After every match Opta completes a video analysis of every touch of the ball. Each action in the match is awarded a points value depending on the relative importance of the action. So for example, a try scores more points than a tackle, but a player loses points for a missed tackle.

The points are then weighted against the score at the time when the action took place (higher points if the score is closer), the time in the match (higher points at the start of the match) and the position on the pitch where it took place (higher points for actions closer to the goal line).

The player is then given a score for the match by adding up all his actions while he was on the field. The total match score is then weighted to take account of the strength of the opposition so that performances across many matches can be judged fairly.

Without further ado...

Australian Conference XV

1. Scott Sio (Brumbies) - the Brumbies' number one has proved his ability in the loose chipping in with 30 carries as well as completing 44/51 tackles.

2. Stephen Moore (Brumbies) - the Brumbies have the best lineout success of any team this season (91%) thanks to this man who has found a teammate with 98 of his 108 lineout throws. The consistent hooker has also proven his worth in open play, completing 75/82 tackles and making 74 carries - the second most of any hooker.

3. Sekope Kepu (Waratahs) - the Waratah prop has maintained a tackle success rate of 93% this season (62/67), and is a real threat in the loose. He has beaten the third-most defenders (8) and made the second-most successful offloads (8) of any prop this season.

4. Luke Jones (Rebels) - Jones has proven himself to be a good all-rounder this season making the second-most carries (124) of any forward and winning the joint fourth most lineouts (43 + 1 steal). He has also made over 100 tackles while maintaining a success rate of 95% (106/112) and won seven turnovers for his side.

5. Will Skelton (Waratahs) - the second rower has continued to be a monster with ball in hand this season, making 113 carries and beating 19 defenders. His ability to dominate the contact area has allowed him to make the most offloads by a forward this season, bringing a teammate into play on 24 occasions with a pass out of the tackle.

6. Sean McMahon (Rebels) - the flanker has beaten the most defenders of any Rebels player this season (26) and has shown an eye for the gap making seven clean breaks in his 11 games. Defensively he is strong as well, with only Michael Hooper (139/157) making more tackles than McMahon (117/128) of players in the Australian Conference.

7. David Pocock (Brumbies) - perhaps the biggest talking point, as David Pocock takes the number seven shirt ahead of Michael Hooper. Pocock is a turnover machine, averaging exactly two per game - more than any other player this season. He has also missed just four of his 102 attempted tackles, and chipped in with 98 carries and 12 defenders beaten and his try-scoring record (4) is a handy bonus.

8. Ben McCalman (Force) - has been his side’s go-to man with ball in hand, making 145 carries - the most of any forward in the league - beating 18 defenders along the way. He is also the Force’s top tackler, making 96 of his 105 attempted tackles.

10. Bernard Foley (Waratahs) - Foley is the third top point scorer this season, and is involved in a try every other game (6 - 3 tries, 3 assists). He has gained the most metres of any half back this season (637), beating 22 defenders and making 15 clean breaks along the way.

11. James O'Connor (Reds) - playing the majority of his games on the wing, O’Connor has beaten the most defenders of any Reds player this season (27) and few players in Super Rugby can better his average of 3.4 beaten per game. He has also turned provider on a number of occasions this season, making five assists in total.

12. Mitch Inman (Rebels) - Inman pipped Kurtley Beale to the 12 shirt, having proven himself to be a dependable, all-round player. He is the only Rebels player to play every minute of his team’s campaign, and has repaid the faith in him by beating 24 defenders, making 11 clean breaks and making 105 tackles while maintaining a 91% tackle success rate. 

13. Samu Kerevi (Reds) - the Reds’ top try scorer with five tries has gained 423 metres from 100 carries, beating 25 defenders on the way. He has also shown his ability without the ball by winning eight turnovers for his team.

He has an impressive average gain of 6.3 metres per carry, gaining 461 metres in total. He has an eye for a gap, making 11 breaks, and has also beaten 11 defenders. He has played the full 80 in every game he has started in this season.

15. Israel Folau (Waratahs) - the top performer this season, Folau has gained more metres than any other player (1217) while only Damian de Allende (49) has beaten more defenders than Folau (44).

3. Charlie Faumuina (Blues) - no prop in Super Rugby 2015 has beaten more defenders than the Blues' number three who has evaded 13 would-be tacklers. He has also offloaded more than any other player in his position (9), while no prop has made more clean breaks than Faumuina either (3). 

4. James Broadhurst (Hurricanes) - a solid all-rounder, Broadhurst has made 94 carries in his 11 appearances, beating 12 defenders and making four clean breaks. He has also offloaded more than any 'Canes player (16) while making over 100 tackles for the Wellington-based side (108/122).

10. Beauden Barrett (Hurricanes) - the top performer in the New Zealand Conference, Barrett has the best average gain of any flyhalf to make at least 10 carries (7.7m) gaining over 600 metres in total.

2. Adriaan Strauss (Bulls) - only four hookers have made more successful lineout throws than Strauss (91/102), who has a better success rate than all but one of the players above him (89%). He has also missed just four of 54 tackles this season and has chipped in with 73 carries in attack.

3. Vincent Koch (Stormers) - the prop completes a front row that is two thirds Stormers, with his side boasting a 92% scrum success this year. He has made 60/66 tackes this season and won four turnovers, proving his defensive worth. His three clean breaks is a joint-high for a prop this season.

The back rower has made more tackles than any other player while maintaining an incredible 97% success rate, missing just six of 194 attempted hits.

14. Cornal Hendricks (Cheetahs) - Hendricks has been one of the Cheetahs’ key men in breaking the defensive line this season, with his 10 clean breaks being two more than any other player in his team.
