Ranger's game has improved this season as he knocked off more of the rough edges in his play. His natural talent has always been evident. His evasive skills are classy, his power frightening and he is one of the nation's best at finding turnover ball in the tackle.
Ranger's attacking instincts can hurt his side at times when he gets too flippant with his ideas instead of playing the percentages. Tweaking that mental application is one of his work-ons, as they say in modern coach-speak.
Where once he might not have reacted well to tuition, Ranger is now very responsive to rugby education. Once he trusts those offering the advice, he is alert and receptive.
The Blues will lament his departure and Ranger is probably feeling a little uneasy as he toils away in the All Blacks.
However, when he gets some space, he will know a $600,000-a-year deal is the right choice for him, his partner and young child. He cannot make that money in New Zealand and there are no guarantees he will stay in the squad or stay injury free.
He has four All Black caps so far in four seasons. It's not a lot but Ranger is an All Black, a member of that revered club, and that is strong currency in Europe.
