Coaches need to encourage their players, nurture and inspire them to achieve their potential.
Sometimes that requires a sharp word in private, perhaps a soothing appraisal and, invariably, a resolute attitude in the face of any criticism.
Those sparring contests are the game within the game as the public and media make their own assessments. In the capital, it is Hammer Time. Coach Mark Hammett has delivered an optimistic prediction about his fourth season in charge.
His continued work as Hurricanes coach needs success this season after an ugly run of 9th, 8th and 11th finishes under his command. Hammett has begun with a vocal flourish.
"I think the youth we had in our team three years ago [has] now gained a lot of experience as both international and Super Rugby players, and I'm confident that group of players will step up this season," he said.
