The TAB's Mark Stafford sits down with some of New Zealand's most prolific and successful sports personalities to find out what makes them tick. This week the man behind the mic is commentator and All Black legend, Justin Marshall.

Marshall is one of the most polarising figures in New Zealand rugby, everyone seems to have an opinion on him. Both as an over-competitive halfback, playing 81 tests, and as an expert commentator on Sky. He talks to Staf about his childhood in Southland, his illustrious career on the field and his new career behind the mic.
