Tom Abercrombie calls it a feud. Mika Vukona admits they just don't like them.

However it's couched, the New Zealand Breakers and Perth Wildcats are enemies on a basketball court - and the animosity will come to a head over the next fortnight as the two teams decide the Australian National Basketball League title in Auckland and Western Australia.
The Breakers host the first of the best-of-three finals series at a near-to-sold-out Vector Arena tonight before the second game in Perth a week on Friday.
A third game will be played in Auckland if required.
