Just as there is no such theme as a friendly in world football, no Port Adelaide-Collingwood match is insignificant - not even a trial game at Football Park in the autumn of 1993.
Port Adelaide faces Collingwood as a sporting rival on Saturday for the 36th time in AFL company, back at the MCG where it all began in 1997. A football legend who has lived each side of the black-and-white divide knows both clubs can find strength in sharing their common backgrounds.
