1. The defence has improved: The Hurricanes truly are a defensive force. They're tough to break down and they've bought in to John Plumtree's new system. They concede 14 points a game; only the Brumbies (13.3) are harder to crack.
Hurricanes assistant coach Clark Laidlaw sparked the shift in mindset among the players during the past couple of seasons and they've taken it to a new level in 2015.
Laidlaw still helps Plumtree with defence but has taken on the attacking portfolio this year.
2. There is a growing maturity: The young guns of the Hurricanes forward pack are now players who have played three or four seasons of Super Rugby. The grind of this competition can be overwhelming for many during their first year but the likes of Ardie Savea, Blade Thomson, Mark Abbott, Reggie Goodes and Brad Shields have continued to evolve. In the backs, No 9 TJ Perenara and first-five Beauden Barrett have developed the ability to control the game and close out tight contests, which was a noted issue for them in the past few years.
