I am a big fan. It requires really good training and really consistent stability in the team structure.
Tick, tick. Both things we seem to have achieved this year.
There is every indication at this stage that training has massively improved since last season. As has been mentioned by several people involved at the club, the sports science agenda has no longer been allowed to prevail. This has meant that drills are run until they're right (and/or the players are exhausted), rather than easing off to circumvent the possibility of injury.
While I don't support either team, I have incredible respect for the coaching systems instituted by both the All Blacks and the Melbourne Storm. Both regimes are reportedly founded on the principle that you need to train as hard (or harder, even) than you play. That way, you are entirely prepared for the rigours of the high-pressure moments in games, where fatigue is off the charts and you just have to execute under enormous duress.
The way we're playing so far this year, it looks to me that we are far better prepared for these moments. And I suspect that significantly increasing the consistent 'ask' at training has been an important part of that improvement.
