Hurricanes to win scenario
As it stands: Third place on 16 points (+7)
Remaining games: v Chiefs, at Highlanders
The scenario: Need to win their remaining two games, both with a bonus point, and hope the Crusaders lose their final two games, and the Blues win their final game without a bonus point, and then have a greater points difference. Basically, they need a miracle.
The 'all three teams finish on the same points' scenario
Yes it's possible. The Crusaders, Blues and Hurricanes could all finish on 26 points.
For this to happen the Crusaders would need to earn just two points from their remaining two games (either a draw against the Highlanders or two bonus points in defeats). The Blues would need to beat the Crusaders without a bonus point (and deny them a bonus point if they head into the game on 26).
The Hurricanes would need the maximum 10 points in victories over the Chiefs and Highlanders. If this did happen then the title would be decided between the Blues and the Hurricanes as they would both have more wins than the Crusaders. Points difference would be the decider.
