Without question there is a link between performance and plain English - that is coaches who make sense in the public arena, make sense behind closed doors when they are talking to their players.
The Blues have been a stunning example of that. Last year Pat Lam confused everyone with his riddles, half answers and non-answers to questions on his tactics and selections. The confusion outside the changing room was nothing in comparison with that inside it - and any side that heads out for battle with most of the players uncertain about what they are doing, are going to be toast in no time.
In came John Kirwan last August and he had a plan: everyone knew he had a plan because he said exactly what it was. Everyone knew what type of players he was looking for and that what he wanted in 2013 was a restoration of passion, commitment and consistent performance.
Results, he said, would not necessarily be critical, as long as the team could engage with their people by playing good, imaginative rugby that showed signs of development from week to week.
Pretty simple vision and no one outside the changing room was left wondering. The 34-20 opening night victory in Wellington is proof that no one inside the changing room was left wondering either.
