The one you've been waiting for, Blindside Flanker.
With Kaino's career winding down this is a huge season for those wearing the six jersey. His replacements last year were unimpressive to say the least. Neither imposed any presence down the blindside channel on defence, with Fifita's workrate inconsistent, and Squire's non-existent. All Black ruck defence was particularly poor last year, and was exploited twice by Australia. Of the two, Fifita has the most athletic potential, though seems better adapted to power lock play at this stage of his career.
The Contenders:
Jerome Kaino - the greatest of all time, does he have another season left? If well managed he probably has a partial one. Must watch injuries though. Will not play all games, even if his form returns dramatically.
Fifita - excellent athlete learning a difficult position. Reminder that Kaino took several years to grow into the position. So did Luatua. Could be the answer, would help to get more time at six this Super Rugby season.
Squire - good ball carrier, flat-track bully. See his performance against the Crusaders in last year's playoff game. Went missing when up against top notch opposition. Very little physical impact in Brisbane against Australia. Needs a massive improvement in workrate and defensive presence.
Ioane - another outstanding young athlete who is still learning the role. Very strong, hits rucks and gains turnovers, physical defender, excellent ball carrier. Needs to improve decision making and workrate consistency. Will play at eight a lot, but has had his best games at six. Future All Black star. Should be developed for the World Cup. Should benefit from his second season playing XVs exclusively.
Hemopo and Evans are the outsiders. Barrett may get some time there for the ABs.
A potential weakness for the All Blacks.
